Description	The position sensor is based on the combination of the eddy-current and permeability effects. The primary field is excited by a coil, but instead of induction coil, the sensing part uses anisotropic magnetoresistor (AMR) which also measures DC magnetic field. As the AMR is being flipped by the excitation frequency, the sensor is self-demodulated and the output is DC. The AMR sensitivity does not depend on frequency; therefore this sensor can be used at ultralow frequencies, where coils fail as sensors. We show the response of our sensor to ferromagnetic and non-ferromagnetic metals and possibilities to distinguish between them. We also show that our sensor can measure position through the conducting sheath. The position sensor is based on the combination of the eddy-current and permeability effects.
