Let us understand this concept by taking an example of electrical machines, as the hysteresis loss occurs mainly where there is reversal of magnetism, as in the magnetic parts of the electrical machines.The temperature of the machine is increased as this loss results in the waste of energy, in the form of heat which is an undesirable process for the machines.Therefore, a suitable magnetic material having a minimum hysteresis loss which has the narrow hysteresis loop is used for making these electrical machinery parts
