摘要： PROBLEM TO BE SOLVED: To provide an easy-to-manufacture magnetic reversing element capable of taking out an induced pulse voltage caused by magnetic reversing, without the need to directly magnetize a target or attach a permanent magnet to the target.
SOLUTION: The magnetic reversing element has a magnetic reversal sensing part 6 formed by winding a coil 4 around a fine magnetic wire 3 having the characteristic of fast magnetic reversing, with a magnetic circuit constructed at a tip of the fine magnetic wire to induce fast magnetic reversal. The pulse voltage induced in the coil 4 by the magnetic reversing is taken out. The outer periphery of the magnetic reversal sensing part 6 is covered with a tube 5 made of a magnetic body, and this combination is positioned on the centerline between the N and S poles of two permanent magnets 1 and 2 spaced apart by a predetermined distance with unlike poles opposing each other.
