MAGNET WITH ELECTROMAGNETIC COIL/IMPEDANCE/SENSOR ELEMENT

摘要

A magnet with electromagnetic coil/impedance/sensor element comprising an electrode wiring board (1) having a groove (11) made to extend in some direction, an electromagnetic coil (3) consisting of one coil (31) formed spirally in the extending groove (11) of the electrode wiring board (1) and the other coil (32) connecting respective upper ends of one coil, an insulator (4) being inserted into the extending groove (11) of the electrode wiring board (1), and a magnetosensitive body (2) inserted into the insulator (4) and being applied with a high frequency or pulse current, and outputting a voltage corresponding to the strength of an external field being generated in the electromagnetic coil upon application of the high frequency or pulse current.
