Abstract
A method of manufacturing a self-nucleating ferromagnetic yarn that exhibits a high degree of coercive force nucleation and that has outer core and core portions that have different magnetic characteristics, including relatively low and high retentivities, respectively, and with a magnetized shell portion having a magnetic field that provides a magnetic bias to magnetize the core portion in a first direction, generally axial, and such that the magnetization of the core portion is reversible against the magnetic polarization of the portion of shell by the application of a separate magnetic field, and the magnetic field of the shell portion being able to act to re-magnetize the core portion in said generally axial first direction by removing said different magnetic field, comprising the steps of heating a ferromagnetic wire up to a first temperature initial high enough to allow the hardening of the yarn by sufficiently rapid cooling of the yarn and cooling the shell and core at relatively fast and slow regimes to provide a relatively soft yarn core and a relatively hard yarn shell with said different magnetic characteristics, respectively, and magnetize the wire wrap in a generally axial direction.
