tailieunhanh - Implementation of an extremely sensitive magnetometer with flux modulation technique

In this work, a highly sensitive low-field magnetometer has been implemented for navigation, electronic compass, and monitoring security. The sensor structure consists of the soft-magnetic core cobalt base, the excitation coil, and the sensing coil. A current passing through the excitation coil at high frequency modulates the permeability of the soft magnetic core. | Implementation of an extremely sensitive magnetometer with flux modulation technique
