Claim:
1. A magnetic structure, comprising: a single piece of magnetizable material comprising neodymium, said single piece of magnetizable material having a first surface and a second surface opposite said first surface, and said single piece of magnetizable material having a thickness between said first surface and said second surface; and a maxel at a location on said first surface of said single piece of magnetizable material, said maxel comprising a first pole having a first polarity and a second pole having a second polarity opposite said first polarity, said first pole of said maxel being substantially exposed on said first surface of said single piece of magnetizable material within a first area about said location, said second pole of said maxel being not substantially exposed on said first surface of said single piece of magnetizable material, said maxel having a depth within said single piece of magnetizable material that is less than or equal to said thickness of said single piece of magnetizable material, said maxel having a magnetic flux density of at least 1500 Gauss as measured at said location on said first surface, wherein a second area of said first surface that is outside said first area is magnetized to have said second polarity, wherein said second area at least partially surrounds said first area.
