Zero Magnetic Field Type Magnetic Field Sensor
IEEJ Transactions on Electronics, Information and Systems, 1990 AbstractThis paper presents a new magnetic field sensor named the zero magnetic field type, on the basis of its principle of operation, which is as follows: when the magnetic field level in the core used as a sensor is shifted by an unknown field to be detected, a controlled field is so superimposed in the opposite direction to the unknown field that ...
