Abstract

The paper explains design, development, and applications of a fluxgate magnetic sensor, which is based on second harmonic Fourier component. The sensor is used to measure an external magnetic DC or low-frequency AC field, B_ext. The probe is driven periodically into saturation by a sinusoidal current that flows through the premagnetization coil. It can be shown that the amplitude of the second harmonic frequency component will be measured by external magnetic field. Some applications of the fluxgate sensor, e.g. non-contact current measurement, vibrations and displacement measurements, have been developed and tested.
