Question:

Which of the following statements are correct ?

(A) Permeability of soft iron < permeability of steel
(B) Susceptibility of soft iron > susceptibility of steel
(C) Retentivity of soft iron > Retentivity of steel
(D) Coercivity of soft iron > coercivity of steel

Choose the correct answer from the options given below:

Options:

(A), (C) and (D) only

(B) and (D) only

(B) only

(C) and (D) only

Correct Answer:

(B) only

Explanation:

The correct answer is Option (3) → (B) only

(B) Susceptibility of soft iron > susceptibility of steel:

Soft iron has a much higher magnetic susceptibility than steel. Susceptibility is a measure of the ease with which a material can be magnetized, and soft iron is easily magnetizable than steel.
