Question

When a ferromagnetic material goes through a hysteresis loop, its thermal energy is increased. Where does this energy come from?

Answer 1

Answer:

Explanation:

When a ferromagnetic material goes through a hysteresis loop, when the magnetization force is applied, the molecules of the magnetic material are aligned in one particular direction, and when this magnetic force is reversed in the opposite direction, work is done to wipe out the residual magnetism. This work done by the magnetizing force produces heat; this wastage of energy in form of heat or thermal energy is known as hysteresis loss.

Answer 2

When a ferromagnetic material goes through a hysteresis loop, its thermal energy is increased. The energy comes from molecular motion within the material.

Explanation:

• When a ferromagnetic material enters through a hysteresis loop when the magnetization force is applied, the molecules of the magnetic material are ranged in one particular direction, and
• when this magnetic force is reversed in the opposite direction, work is done to wipe out the leftover magnetism.
• This work done by the magnetizing force gives rise to heat and this wastage of energy in the form of heat or thermal energy is known as hysteresis loss.
