Abstract
A geomagnetic sensor includes: a core that constitutes a closed magnetic circuit; a pair of coils that are wound around the core in positions facing each other and are connected in series to generate magnetic flux in the same circumferential direction in the core; an excitation power supply that applies an alternating current with a superimposed direct current to the pair of coils; and a detection circuit that is connected to a connection point of the pair of coils. Unlike a conventional flux gate type geomagnetic sensor, it is not required to excite the core until the core is magnetically saturated, and it is therefore possible to reduce power consumption.
