DEVICE FOR MEASURING WEAK MAGNETIC FIELDS BASED ON EFFECT OF GIANT MAGNETIC IMPEDANCE Russian patent published in 2019 - IPC G01R33/02 

FIELD: measuring equipment.

SUBSTANCE: invention relates to the field of measurement technology and can be used to measure weak magnetic fields. Device for measuring weak magnetic fields based on the effect of a giant magnetic impedance contains a magnetically sensitive element, made of two identical amorphous ferromagnetic microwires in a glass shell or with a remote glass shell placed inside one multi-turn coil, high-frequency excitation of microwires is carried out from a multi-turn coil, and registration of signals from two microwires is performed using a differential amplifier.

EFFECT: improving the accuracy of measurements, reducing the systematic error of the output signal of the magnetometer as a whole.
