ABSTRACT:
A Wiegand wire module is excited by a non-uniform field, which may vary in time either symmetrically or asymmetrically, to provide a switch in state of the Wiegand wire thereby inducing a pulse in the pickup coil of the module. The non-uniform field has a maximum value in an axial direction at a center portion of the wire and a minimum value in an axial direction at end portions of the wire. As the amplitude of the field is varied to switch the wire, the end portions of the wire remain in a field having a low axial magnitude. The result is an output pulse substantially greater than obtained through symmetric exitation using a uniform field.
