Abstract
A pulse generating element formed of a switchable magnetic wire is worked so as to have an arcuate shape such that the ratio R/d between the radius of curvature R and diameter d of the wire in a state free from external force ranges from 65 to 95. This is achieved by subjecting a wire of a ferromagnetic material, such as Fe--Co--V, to drawing-bending work. The pulse generating element, which is obtained by cutting the switchable magnetic wire to a predetermined length, is restricted to a substantially straight state by a retaining member, and undergoes a drastic flux reversal when it is subjected to an alternating field.
