MAGNETIC FIELD DETECTION METHOD, MAGNETIC SENSOR, AND BIOMAGNETIC SENSOR

摘要

PROBLEM TO BE SOLVED: To provide a magnetic field detection method for detecting a measurement target magnetic field.SOLUTION: A magnetic field detection method includes: a first step of applying a first application magnetic field to a magnetic field measurement part, in a state where a measurement target magnetic field is applied; a second step of applying a second application magnetic field different from the first application magnetic field to the magnetic field measurement part, in the state where the measurement target magnetic field is applied; and a third step of detecting the measurement target magnetic field according to a first output signal outputted from the magnetic field measurement part at the first step and a second output signal outputted from the magnetic field measurement part at the second step.SELECTED DRAWING: Figure 2
