Rotation magnetization reversal fluxgate excited by the voltage source

Fluxgate with rotation magnetization reversal of the isotropic disk core under the harmonic voltage source excitation has been analysed and the model of the response on the measured field components has been developed. When the excitation frequency is a half of the excitation circuit resonance frequency, the fluxgate sensitivity increases quadratically with the frequency and can exceed the sensitivity of the current driven fluxgate.
