  • Device for measuring a magnetic field, associated system and method
    Patent number: 12061245
    Abstract: This device for measuring a magnetic field comprises: a magnetic field sensor, comprising: a probe, and a pick-up coil and a feedback coil coiled around the probe, and a control circuit, comprising: a generation module comprising a probe signal generation unit, configured to generate an electrical current, a preamplification module, a buffer module, configured to deliver an output signal of the control circuit defining an output magnetic field value, a piloting module configured to pilot the probe signal generation unit to generate the electrical current in the probe. The control circuit comprises a correction module configured to control a working magnetic field, corresponding to a magnetic field maximizing the magnetic field sensitivity of the probe and minimizing the magnetic field noise of the probe.
