ABSTRACT:
A magnetic direction detecting apparatus has a magnetic sensor head composed of a magnetic core, an exciting coil wound around the core and a pair of detection coils diametrically wound around the core perpendicularly to each other; an oscillator for supplying a rectangular current wave of a single polarity to the exciting coil; and a switching gate openable synchronously with the rectangular wave for permitting only peaks of the same polarity to pass therethrough. The detection of a magnetic direction by using this apparatus does not suffer from restrictions in switching gate-opening timing.
