A fluxgate magnetometer works by exploiting the nonlinear magnetic response of a ferromagnetic core to detect an external magnetic field. It detects changes in magnetic permeability due to the presence of an external field, typically producing a signal at 2nd harmonic of the excitation frequency. In a fluxgate sensor, the core material has very high magnetic permeability <math>\mu</math>. This means, the core material can..."
