A) This effect is common to all ferromagnetic substances
B) The hysteresis loop area is proportional to the thermal energy developed per unit volume of the material
C) The hysteresis loop area is independent of the thermal energy developed per unit volume of the material
D) The shape of the hysteresis loop is characteristic of the material
Correct Answer: C
Solution :
