Operating principle

Measuring system to determine the coercive field strength of magnetic materials in an open magnetic circuit. A magnetic sample is placed in a coercimeter coil and magnetized up to saturation. The polarization is measured by fluxgate probes. Determination of coercive field strength is to be done by demagnetization of the sample till zero polarization is reached. The measured field strength at that point is the coercive field strength HcJ.
