What is Hysteresis Loop? What is its significance?
Asked by Topperlearning User | 21 May, 2015, 01:53: PM
answered-by-expert Expert Answer
 
When a specimen of magnetic material is magnetised, a curve is drawn for magnetic field intensity (H) against intensity of magnetisation (I). The curve so formed is called Hysteresis Loop. This complete process is called Cycle of Magnetisation. It is called hysteresis because of lagging of I behind H during the cycle of magnetisation.
 
The area of the loop gives the energy loss per unit volume of the specimen per cycle of magnetisation.
 
The hysteresis loop of different materials is used to compare retentivity, coercivity and energy loss. Therefore, a suitable material is selected for making electromagnets, transformers, permanent magnets, generator etc.
