Abstract
Hardware that uses plug-in detectors and allows one to measure coercive force in the range of few to several hundred A/m in industrial products of different shapes is presented. The operating principle is based on a functional relationship between the tangential component of the magnetic field close to the surface of a residually magnetized article and the coercive force of the article material as well as a connection between the gradient of the field of a magnetic pole formed at the article surface after local magnetization and the coercive force.
