Abstract
A non-linear multi-pole magnetization pattern is used to magnetize flexible magnetizable sheets. The non-linear pattern is produced by a magnetizing mechanism having a set of angled magnets. Shifting of magnetic sheet positions in a stack is eliminated by randomizing the positions of the multiple magnetic poles in such manner that as the magnetic sheets are stacked, each sheet will have a multi-pole configuration different from the adjacent sheets below and above it on the stack.
