Abstract
Mechanically controllable magnet made of a magnetostrictive, circularly magnetically anisotropic, circularly magnetized rod. There is no apparent magnetism externally. When rod is twisted, circular anisotropy becomes helical and circular magnetization also becomes helical to produce an axial field component and hence externally apparent magnetism. When rod untwists, it restores itself to its apparently non-magnetic condition.
Claims13
A mechanical magnet, comprising a rod of magnetostrictive, remanent, circularly magnetically anisotropic, circularly magnetized material, and means for twisting said rod, whereby to alter said circular anisotropy to helical anisotropy and thus reorient the circular magnetic field to a helical field with an axial component.
