SPICE simulation of coupled core fluxgate magnetometers

SPICE simulation is universally recognized as a powerful tool in the field of electronic engineering. These simulations are, particularly useful for dealing with a strong nonlinear behavior that cannot be easily handled analytically. Magnetic hysteresis is one example of a non-linearity that underpins many practical applications, especially in the field of magnetometers and magnetic sensors. The aim of this paper is to present a behavioral model of magnetic hysteresis applied to the numerical simulation of coupled core fluxgate magnetometers.
