Hysteresis loops for two magnetic materials A and B are given below:

These materials are used to make magnets for electric generators, transformer core and electromagnet core. Then it is proper to use:
Text Solution
Verified by ExpertsThe correct answer is:
C
Area of hysteresis loop is proportional to net energy absorbed per unit volume by the material, as it taken over a complete cycle of magnetisation.
For electromagnets and transformers energy loss should be low.
i.e., thin hysteresis curves.
Also
, when
and
should be small when
