Abstract:
A high energy magnetizer/demagnetizer in combination with a non-operative portion of a driving tool or the like, comprising at least one permanent magnet formed of a magnetized material having north and south poles defining a magnetic axis and arranged on the non-operative portion of the driving tool or the like to permit selective placement of a magnetizable element at at least one position along said magnetic axis at a predetermined distance from one of said poles to magnetize the element and placement of the magnetizable element at one of a plurality of selected distances from the other of said magnetic poles each greater than said predetermined distance to selectively demagnetize the element; and indicia means on the non-operative portion of the driving tool or the like for providing an indication of a desired or preferred position for placement of the magnetizable element to be demagnetized as a function of the relative size of the portion of the magnetizable element to be demagnetized, whereby a magnetizable element of a given size may be initially magnetized by positioning same adjacent to one of said poles mounted on the non-operative portion of the driving tool or the like and subsequently substantially or fully demagnetized by positioning the magnetizable element at a selected distance from the other of said poles as indicated by said indicia means.
