Which of the following statements is incorrect about hysteresis
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
Answer
The hysteresis loop area is independent of the thermal energy developed per unit volume of the material
Explanation
Solution
The energy lost per unit volume of a substance in a complete cycle of magnetisation is equal to the area of the hysteresis loop.
