Ferrite hysteresis curve
Since a coercive force must be applied to overcome this residual magnetism, work must be done in closing the hysteresis loop with the energy being used being dissipated as heat in the magnetic material. This heat is known as hysteresis loss, the amount of loss depends on the materials value of coercive force. See more Previously, the relative permeability, symbol μr was defined as the ratio of the absolute permeability μ and the permeability of free space μo (a vacuum) and this was given as a constant. However, the … See more By plotting values of flux density, ( B ) against the field strength, ( H ) we can produce a set of curves called Magnetisation Curves, Magnetic Hysteresis Curves or … See more However, the magnetic flux does not completely disappear as the electromagnetic core material still retains some of its magnetism even when the current has stopped … See more The set of magnetisation curves, M above represents an example of the relationship between B and H for soft-iron and steel cores but every type of core material will have its own set of magnetic hysteresis curves.
