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:
Answer & explanation
Correct answer: option 3
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.
