Abstract
A magnetization method and apparatus is described as utilizing a pair of mechanically counter-vibrated permanent magnets having mutually facing unlike magnetic poles, and wherein a ferromagnetic article, or article containing ferromagnetic elements in close-set array, is placed for subjection to pulsed magnetizing flux between the pair of counter-vibrated magnets. Uses of the invention include making magnets and modifying the current drain property of a multi-plate nickel-metal hydride battery.
