Magnetic hysteresis occurs when an external magnetic field is applied to a ferromagnet such as iron and the atomic dipoles align themselves with it. Even when the field is removed, part of the alignment will be retained: the material has become magnetized. Once magnetized, the magnet will stay magnetized indefinitely. To demagnetize it requires heat or a magnetic field in the opposite … WebWasp-waisted behavior in magnetic hysteresis curves of CoFe 2 O 4 nanopowder at a low temperature: experimental evidence and theoretical approach.
