METHOD FOR PRODUCING A MAGNETIC SWITCHING ELEMENT, WHICH RE-MAGNETIZES FAST, EVEN WITH SLOW FIELD CHANGE

摘要

A process for the manufacture of a magnetic switch element is specified. A fine-crystalline structure is produced by short-term annealing of a cobalt-iron-vanadium alloy at 630 to 900 DEG C, which leads to pulse voltages of over 10 volts when subjected to a slowly changing field under tensional stress in a coil with 1000 windings. This property is reproducible so that inductively operating sensors can be manufactured, for example, for speed transmitters operating down to zero speed.
