Abstract :
A simple and inexpensive magnetometer is presented which uses a piezomagnetic primary sensor together with a piezoelectric transducer to convert a magnetic field into an electrical signal. A linear operating range is achieved by employing a negative feedback configuration. The detection sensitivity is 1.5 x 10-4 A/m per Hz1/2at low frequencies.
