Question

Hard ferromagnetic material is characterized by,

• A. Narrow hysteresis loop
• B. Broad hysteresis loop
• C. Absence of hysteresis
• D. Either $\left(A\right)$ or $\left(B\right)$

Answer 1

The correct option is B Broad hysteresis loop

The hard ferromagnetic material is characterized by broad hysteresis loop, which results in large area of hysteresis curve. Thus, these materials are also suitable for permanent magnets.

Hence, option $\left(B\right)$ is the correct answer.
