What is hysteresis loss? Where does the loss actually occur?

An electric current through a wire wound into a coil creates a magnetic field through the center of the coil, due to Ampere's circuital law. Coils are widely used in electronic components such as electromagnets, inductors, transformers, electric motors and generators. A coil without a magnetic core is called an "air core" coil. Adding a piece of ferromagnetic or ferrimagnetic material in the cente… WebHysteresis Loss, Resistivity, p, (core loss) The enclosed area within the hysteresis, shown in Figure 2-1, is a measure of the energy lost in the core material during that cycle. This loss is made up in two components: (1) the hysteresis loss and (2) eddy current loss. The hysteresis loss is the energy loss when the magnetic material is going ...

WebHysteresis loss is undesirable in electrical machines as it produces heat and is responsible for the loss of energy, thus creating further temperature rise. Since hysteresis loss is proportional to the area of the hysteresis loop, the loss is kept low by using materials having narrow hysteresis loops. Silicon is added to steel for this purpose.
