Magnetic noise contribution of the ferromagnetic core of induction magnetometers

Magnetic noise contribution of the ferromagnetic core of induction magnetometers

The performance of induction magnetometers, in terms of resolution, depends both on the induction sensor and the electronic circuit. To investigate accurately the sensor noise sources, an induction sensor, made of a ferrite ferromagnetic core, is combined with a dedicated low voltage and current noi...
