Abstract
A new type of the compound magnetic wire sensor is developed. A search coil is wound around the wire which has a uniaxial magnetic anisotropy along the axis direction of the wire. In order to apply a negative magnetic field to the wire, two pieces of cylindrical Ba ferrite magnets are appended at the both ends of the wire. The sensor induces a constant pulse voltage of about 0.7 mV/turn which is independent of the changing rate of the positive external exciting field. The sensor consisted of the compound magnetic wire and 3000 turns search coil induces a stable output voltage of about 2V. It is also advantageous that this simple-structure sensor can be fabricated at a low cost.
