Abstract

A magnetic field detecting device which comprises a magnetic impedance sensor including a magnetic impedance elementin which a pulse electrical current or a high frequency electrical current is applied from an oscillatorto an amorphous wireand an alternate current or AC damped oscillation voltage, which is induced in a detecting coilwound around the amorphous wireand has a magnitude corresponding to an external magnetic field, is output, and an arbitrary magnetic field is applied to the amorphous wire by means of the magnetic field generated on the detecting coilenergized by connecting the detecting coilto a voltage source or to a current source E through an impedance networkcomprising of a resistor R or a coil L or a condenser C or comprising a combination of the resistor R, the coil L, and the condenser C.
