Diamagnetic hysteresis loop
Did you know?
Diamagnetic materials are repelled by a magnetic field; an applied magnetic field creates an induced magnetic field in them in the opposite direction, causing a repulsive force. In contrast, paramagnetic and ferromagnetic materials are attracted by a magnetic field. Diamagnetism is a quantum mechanical effect that occurs in all materials; when it is the only contribution to the magnetism, the material is called diamagnetic. In paramagnetic and ferromagnetic substances, … WebThere are three types of magnetic hysteresis curves. The first one is the major hysteresis curve, which depicts the variation in magnetic induction in the sample magnetized by the …
