The present inventors have recognized, among other things, that a problem to be solved may also include preventing a magnetic device from reorienting itself when exposed to external magnetic fields. The present inventors have recognized, among other things, that a problem to be solved may also include preventing a magnetic device from reorienting itself when placed in closed proximity to a ferrous material.

The system for storing magnetic materials may include a magnetic device and an apparatus for storing magnetic materials. The apparatus for storing magnetic materials may include a tray. The apparatus for storing magnetic materials may include a sheet. The apparatus for storing magnetic materials may include a first set of height modulators. The apparatus for storing magnetic materials may include a diamagnetic material. The apparatus for storing magnetic materials may include a ferromagnetic material. 
     The tray may include one or more pockets. The one or more pockets may be configured to receive a magnetic device. The sheet may be configured to couple with the tray.

     The apparatus for storing and transporting magnetic materials may allow for magnetic devices to be stored in close proximity by using the diamagnetic material and/or the ferromagnetic material to localize the attractive forces between the magnetic devices. The magnetic devices may be in a JEDEC tray or arranged along a flat plane. Localizing the attractive forces may include dissipating the attractive forces between the magnetic devices such that a first magnetic device, positioned within a first pocket, may not cause a second magnetic device, positioned within a second pocket, to reorient itself within the second pocket (or vice-versa). 
     The apparatus for storing magnetic materials may allow for the position or orientation of magnetic devices to remain unchanged when exposed to external magnetic fields, such as by using the diamagnetic material and/or the ferromagnetic material to diminish the interaction of the external magnetic fields with the magnetic devices.

     Each of these non-limiting examples may stand on its own, or may be combined in various permutations or combinations with one or more of the other examples. This overview is intended to provide an overview of subject matter of the present patent application. It is not intended to provide an exclusive or exhaustive explanation of the invention. 
       FIG. 1  illustrates a portion of a system  100  for storing magnetic devices. The system  100  may include an apparatus  105  for storing magnetic devices. The system  100  may include more than one apparatus  105 . The apparatus  105  may include a tray  110 . The tray  110  may include a first section  120 . The tray  110  may include a second section  130 . The tray  110  may include interconnection features  170 . The interconnection features  170  may allow for the tray  110  to couple, or mate, with additional elements, such as a second apparatus (not shown). The interconnection features  170  may allow for the tray  110  to couple, or mate, with a JEDEC tray. Stated another way, the tray  110  (or the apparatus  100 ) may be configured to comply with the standards defining the dimensions and features of a JEDEC tray. 
     The first section  120  of the tray  110  may include one or more pockets. The second section  130  of the tray  110  may include a one or more pockets. The first section  120  may include a first set of pockets  140 . The second section  130  may include a second set of pockets  150 . The first set of pockets  140  may have a first set of dimensions. The second set of pockets  150  may have a second set of dimensions. The first set of dimensions may be the same as the second set of dimensions. The first set of dimensions may be different than the second set of dimensions. 
     The dimensions of the first set of pockets  140  may include a first length and a first width. The dimensions of the second set of pockets  150  may include a second length and a second width. The first length and the first width may differ from the second length and the second width. The first length and the first width may differ from the second length and the second width depending upon the dimensions of the magnetic devices (not shown) that will be positioned within the first set of pockets  140  or the second set of pockets  150 , respectively. In an example, the dimensions of the first set of pockets  140  are configured to accept a first magnetic device (not shown) within each of the pockets of the first set of pockets  140 . The dimensions of the second set of pockets  150  are configured to accept a second magnetic device (not shown) within each of the pockets of the second set of pockets  150 . The first magnetic device may be smaller than the second magnetic device. 
     As shown in  FIG. 1 , the first set of pockets  140  and the second set of pockets  150  are generally rectangular in shape. However, the present subject matter is not so limited. The first set of pockets  140  or the second set of pockets  150  may be generally circular, triangular, square, or any other nth-sided polygon in shape. 
       FIG. 2  illustrates a different portion of the system  100  for storing magnetic devices of  FIG. 1 . The system  100  may include the apparatus  105 . The apparatus  105  may include the tray  110 . The tray  110  may include one or more pockets, such as a pocket  200 . The pocket  200  may be included in the first set of pockets  140  of  FIG. 1 . The pocket  200  may be included in the second set of pockets  150  of  FIG. 1 . 
     The pocket  200  may include pocket sidewalls  210 . The pocket sidewalls  210  may define a cavity  215  (e.g., a top opening). The pocket  200  may include a chamfered surface  220 . The pocket  200  may include a recess  230 . The recess  230  may be configured to have dimensions similar to a magnetic device (not shown), such that a small clearance is provided between the magnetic device and the recess  230 . The chamfered surface  220  may provide an angled surface that extends from the pocket sidewalls to the recess  230 . The chamfered surface  220  may reduce the area of the cavity from a first area, to a second area. The top of the cavity may have the first area. The recess may have the second area. The chamfered surface  220  may ease the placement of the magnetic device within the cavity of the pocket  200 . The chamfered surface  220  may ease the positioning of the magnetic device within the recess  230 . The pocket  200  may include an opening  235 . The opening  235  may extend into the cavity  215 . 
     The apparatus  105  may include a sheet  240 . The sheet  240  may be configured to couple with the tray  110 . The sheet  240  may be located adjacent to a bottom  270  of the one or more pockets. Stated another way, coupling the sheet  240  with the tray  110  may define the bottom of the pocket  200 . The diamagnetic material or the ferromagnetic material may be located adjacent to a bottom of at least one pocket  200 . 
     The apparatus  105  may include a height modulator  250 . The sheet  240  may include a height modulator  250 . The height modulator  250  may be disposed between at least one pocket bottom and the diamagnetic or ferromagnetic material. The opening  235  may be configured to receive the height modulator  250 . Reception of the height modulator  250  by the opening  235  may define the bottom of the pocket  200 . The sheet  240  may include one or more (or a set) of the height modulator  250 . The height modulator  250  may protrude from a surface of the sheet  240 . The height modulator  250  may be configured to extend into the pocket  200  at a first distance. The height modulator  250  may be configured to extend into the pocket  200  at a second distance (e.g., have a varying height). The height of the height modulator may define the height of the recess  230 . Stated another way, the distance that the height modulator  250  extends into the pocket  200  may define the height of the recess  230 . 
     The apparatus  105  may include a spacer  260 . The spacer  260  may mate with the height modulator  250  (or one or more of the height modulator  250 ) such that an overall height of the height modulator  250  is reduced. The spacer  260  may be configured to alter the distance that the height modulator  250  extends into the pocket  200 . Altering the distance that the height modulator  250  extends into the pocket  200  may alter the height of the recess  230 . The spacer  260  may mate with the tray  110 . The spacer  260  may mate with the sheet  240 . The spacer  260  may be positioned between the tray  110  and the sheet  240 . In an example, positioning the spacer  260  between the tray  110  and the sheet  240  configures a first set of height modulators to protrude into one or more pockets at a second distance, wherein the second distance is less than a first distance that the first set of height modulators originally (e.g., before the spacer  260  was implemented) extended into the one or more pockets. 
       FIG. 3  illustrates a different portion of the system  100  for storing magnetic devices of  FIG. 1 . As described herein, the system  100  may include the apparatus  105 . The apparatus  105  may include a sheet  340 . The sheet  340  may be the sheet  240  of  FIG. 1 . The sheet  340  may include a first height modulator  350 A. The sheet  340  may include a second height modulator  350 B. The first height modulator  350 A may be the height modulator  250  of  FIG. 2 . The second height modulator  350 B may be the height modulator  250  of  FIG. 2 . The first height modulator  350 A may be the same height as second height modulator  350 . The first height modulator  350 A may be a different height as second height modulator  350 B. The first height modulator  350 A may have a first length and a first width. The second height modulator  350 A may have a second length and a second width. The first width may be the same as the second width. The first width may be different than the second width. The first length may be the same as the second length. The first length may be different than the second length. 
     The sheet  340  may be a first sheet. The apparatus  105  may include a second sheet (not shown). The second sheet may include all of the features or elements of the first sheet. The second sheet may have differing dimensions (e.g., a length, a width, or a height) than the first sheet. The first sheet may be configured to couple with the first section  120  of the tray  110  of  FIG. 1 . The second sheet may be configured to couple with the second section  130  of the tray  110  of  FIG. 1 . Use of the first sheet and the second sheet may allow for the tray  110  to accommodate magnetic devices of varying dimensions and/or shapes. The first sheet may be configured to couple with only the first set of pockets  140 , instead of all of the sets of pockets of the first section  120 . Stated another way, the sheet  340  may be configured to couple with various sections, or sub-sections, of the tray  110  of  FIG. 1 . 
     The tray  110  or the sheet  340  may include a composite material. The composite material may include a dielectric matrix. The dielectric matrix may include a plastic material. The dielectric matrix may be injection moldable. The composite material may include a dispersed phase. The dispersed phase may include a diamagnetic material and/or a ferromagnetic material. The volumetric ratio of the dielectric matrix to the dispersed phase may vary. The volumetric ratio of the diamagnetic material and/or the ferromagnetic material within the dispersed phase may vary. The dielectric matrix may include liquid crystal polymers, carbon tube filled liquid crystal polymers, and/or polyphenylene oxide. The diamagnetic material may include bismuth, gold, copper, silver, mercury, and/or lead. The diamagnetic material may be selected from the group consisting of bismuth, gold, copper, silver, mercury, and lead. The ferromagnetic material may include iron, nickel, cobalt, and/or gadolinium. The ferromagnetic material may include an alloy of iron, nickel, cobalt, and/or gadolinium. The ferromagnetic material may be selected from the group consisting of iron, nickel, cobalt, and gadolinium. 
     Use of the composite material may allow for the apparatus  105  to localize the attractive forces between adjacent magnetic devices (e.g., in an adjacent pocket) positioned within the apparatus  105  or from external influences (e.g., external magnetic forces or magnetic materials). Localization of the attractive forces may be provided by the dispersed phase within the dielectric matrix. The dispersed phase may allow for the relative isolation of attractive forces caused by a proximate magnetic device. 
     In an example, the apparatus  105  of  FIGS. 1-2  includes a sheet of ferromagnetic material coupled to the bottom of the tray  110 . Coupling a plurality of magnetic devices to the apparatus  105  may result in a build-up of magnetic forces within the ferromagnetic material. When the magnetic forces build-up within the ferromagnetic material, the amount of force necessary to remove an individual magnetic device from the apparatus  105  may increase. Stated another way, coupling a plurality of magnetic devices to the apparatus  105 , that includes the ferromagnetic material, may make it more difficult to remove an individual magnetic device from the apparatus  105 . This is in contrast with the lesser amount of force that would be necessary if just the individual magnetic device were coupled to the apparatus  105 . The amount of force necessary to remove an individual magnetic device from the apparatus  105  may increase to a point where it becomes difficult for a pick-and-place apparatus to remove an individual magnetic device from the apparatus  105 . 
     In contrast, the sheet  340  may include the diamagnetic material and/or the ferromagnetic material. The sheet  340  may be coupled to the bottom of the tray  110  of  FIGS. 1-2 . The inclusion of the diamagnetic material and/or the ferromagnetic material may allow for the localization of the magnetic forces that are generated when one or more magnetic devices are coupled to the apparatus  105 . Localization of the magnetic forces may prevent the build-up of magnetic forces within the sheet  340 . Preventing the build-up of magnetic forces within the sheet  340  may prevent an increase in force that is necessary to remove an individual magnetic device from the apparatus  105  when a plurality of magnetic devices are coupled to the apparatus  105 . Stated another way, coupling a plurality of magnetic devices to the apparatus  105 , that includes the sheet  340 , may allow for a localization of magnetic forces generated by the individual magnetic devices. 
     Localizing the magnetic forces may prevent a build-up of magnetic charge within the sheet  340 . Localizing magnetic forces may maintain the amount of force necessary to remove an individual magnet from the apparatus  105  such that adding additional magnetic devices to the apparatus  105  has a minor, or no, effect upon the amount of force necessary to remove individual magnets from the apparatus  105 . Inclusion of the diamagnetic material and/or the ferromagnetic material may allow for the pick-and-place apparatus (or other machines or individuals) to remove an individual magnetic device from the apparatus  105 , regardless of the number of magnetic devices coupled to the apparatus  105 . 
     In another example, the height modulators (e.g., the height modulator  250  of  FIG. 2 , the first height modulator  350 A, or the second height modulator  350 B) may allow for the fine-tuning, or modulation, of the magnetic/attractive forces between a magnetic device (not shown) and the sheet  340 . The height modulators  350 A or  350 B may include the diamagnetic material and/or the ferromagnetic material. The height modulators  350 A or  350 B may not include the diamagnetic material and/or the ferromagnetic material. Increasing the distance between the magnetic device and the sheet  340  may decrease the amount of magnetic forces that are generated between the sheet  340  and the magnetic device, thereby decreasing the holding force of the magnetic device within the apparatus  105 . By varying the height of the height modulators, the amount of force that is generated between the magnetic device and the sheet  340  may be varied. Varying the amount of force that is generated between the magnetic device and the sheet  340  may allow for the fine-tuning of the amount of force necessary to remove the magnetic device from the apparatus  105 . 
     The apparatus may include varying heights of height modulators, thereby allowing for a variety of magnets, with varying strengths, to be stored within an individual tray  110  of the apparatus  105 . As described herein, the localization of the magnetic forces within the apparatus  105  may also prevent adjacent magnetic devices from influencing one another. In an example, a first magnetic device is placed within a first pocket, and a second magnetic device is positioned within a second pocket, wherein the first pocket is located adjacent to the second pocket. If a diamagnetic material were not included in the apparatus  105 , the first magnet may be able to influence the second magnet (or vice-versa), thereby causing the second magnet to reorient itself, or otherwise move out of a desired position. 
     By including a diamagnetic material within the apparatus  105 , the magnetic forces generated by the first magnet are localized within the first pocket such that the amount of influence the first magnet is able to exert upon the second magnet may be significantly, if not entirely, reduced. Inclusion of the diamagnetic material and/or the ferromagnetic material within the apparatus  105  may prevent the magnetic devices coupled to the apparatus  105  from reorienting themselves or otherwise moving out of a desired position. Reducing the amount of influence between adjacent magnetic devices may allow for the number of magnetic devices per unit area that are coupled with the apparatus  105  to increase, because undesirable inter-magnetic device influences are minimized or eliminated. Inclusion of the diamagnetic material may also shield the magnetic devices coupled to the apparatus  105  from external influences, such as external magnetic fields or magnetic objects that are located proximate the apparatus  105 . 
     As discussed herein, a spacer (e.g., the spacer  260  of  FIG. 2 ) may also be used to vary the heights of one or more height modulators, thereby allowing for a variation of the attractive forces between devices positioned within a pocket (e.g., the pocket  200  of  FIG. 2 ) and the sheet  340 . 
       FIG. 4  illustrates a different portion of the system for storing magnetic devices of claim  1 . The system  100  may include the apparatus  105 . The apparatus  105  may include the tray  110 . The tray  110  may include one or more pockets, such as a pocket  200 . The pocket  200  may include pocket sidewalls  210 . The pocket sidewalls  210  may define a cavity  215  (e.g., a top opening). The pocket  200  may include a chamfered surface  220 . The pocket  200  may include a recess  230 . 
     The pocket  200  may include a first cutout  400 A. The pocket  200  may include a second cutout  400 B. The pocket may include additional cutouts. The first cutout  400 A and/or the second cutout  400 B may extend into the pocket sidewall  210 . The first cutout  400 A and/or the second cutout  400 B may be a hole that extends into the pocket sidewall  210  normal to a top surface of the pocket  210 . The first cutout  400 A and/or the second cutout  400 B may remove material from the pocket sidewall  210  and the chamfered surface  220 . The first cutout  400 A and/or the second cutout  400 B may extend from the recess  230  into the pocket sidewall  210 . 
     The first cutout  400 A and the second cutout  400 B may be positioned on opposite sides of the pocket  200 . Additional cutouts may be located on the pocket sidewalls  210  that do not include the first cutout  400 A and the second cutout  400 B. The first cutout  400 A and/or the second cutout  400 B may be configured to receive a pin. Although the first cutout  400 A and the second cutout  400 B shown in  FIG. 4  are generally circular in cross-sectional shape, the invention is not so limited. The cutouts may be triangular, square, rectangular, or any other nth-sided polygon in cross-sectional shape. 
     The system  100  may include the magnetic device  410 . The magnetic device  410  may mate with the bottom  270  of the pocket  200 . The bottom  270  of the pocket  200  may be the top surface of a height modulator (e.g., the height modulator  250  of  FIG. 2 , the height modulator  350 A of  FIG. 3 , or the height modulator  350 B of  FIG. 3 ). Positioning the magnetic device  410  within the pocket  210  may be eased by the chamfered surface  220 . The magnetic device  410  may reside within the recess  230  during storage. The recess  230  may be sized and shaped (e.g., have dimensions slightly larger than the magnetic device  410 ) to contribute to the prevention of the movement (or reorientation) of the magnetic device  410  within the pocket  200 . 
     VARIOUS NOTES 
     The above description includes references to the accompanying drawings, which form a part of the detailed description. The drawings show, by way of illustration, specific embodiments in which the invention may be practiced. These embodiments are also referred to herein as “examples.” Such examples may include elements in addition to those shown or described. However, the present inventors also contemplate examples in which only those elements shown or described are provided. Moreover, the present inventors also contemplate examples using any combination or permutation of those elements shown or described (or one or more aspects thereof), either with respect to a particular example (or one or more aspects thereof), or with respect to other examples (or one or more aspects thereof) shown or described herein. 
     In the event of inconsistent usages between this document and any documents so incorporated by reference, the usage in this document controls. 
     In this document, the terms “a” or “an” are used, as is common in patent documents, to include one or more than one, independent of any other instances or usages of “at least one” or “one or more.” In this document, the term “or” is used to refer to a nonexclusive or, such that “A or B” includes “A but not B,” “B but not A,” and “A and B,” unless otherwise indicated. In this document, the terms “including” and “in which” are used as the plain-English equivalents of the respective terms “comprising” and “wherein.” Also, in the following claims, the terms “including” and “comprising” are open-ended, that is, a system, device, article, composition, formulation, or process that includes elements in addition to those listed after such a term in a claim are still deemed to fall within the scope of that claim. Moreover, in the following claims, the terms “first,” “second,” and “third,” etc. are used merely as labels, and are not intended to impose numerical requirements on their objects. 
     Geometric terms, such as “parallel”, “perpendicular”, “round”, or “square”, are not intended to require absolute mathematical precision, unless the context indicates otherwise. Instead, such geometric terms allow for variations due to manufacturing or equivalent functions. For example, if an element is described as “round” or “generally round,” a component that is not precisely circular (e.g., one that is slightly oblong or is a many-sided polygon) is still encompassed by this description. 
     Method examples described herein may be machine or computer-implemented at least in part. Some examples may include a computer-readable medium or machine-readable medium encoded with instructions operable to configure an electronic device to perform methods as described in the above examples. An implementation of such methods may include code, such as microcode, assembly language code, a higher-level language code, or the like. Such code may include computer readable instructions for performing various methods. The code may form portions of computer program products. Further, in an example, the code may be tangibly stored on one or more volatile, non-transitory, or non-volatile tangible computer-readable media, such as during execution or at other times. Examples of these tangible computer-readable media may include, but are not limited to, hard disks, removable magnetic disks, removable optical disks (e.g., compact disks and digital video disks), magnetic cassettes, memory cards or sticks, random access memories (RAMs), read only memories (ROMs), and the like. 
     The above description is intended to be illustrative, and not restrictive. For example, the above-described examples (or one or more aspects thereof) may be used in combination with each other.
