NEET Physics (general) MCQ Question

Type: MCQ-conceptual-Easy-Class 12

Which of the following statements about electromagnetic induction is correct?

A

The energy stored in a magnetic field is proportional to the square of the magnetic field strength.

B

Mutual inductance can only occur between coils that are very close to each other.

C

The emf induced in a coil is independent of the rate of change of magnetic flux.

D

Self-inductance does not depend on the physical dimensions of the coil.

Correct Answer

Option A

Detailed Explanation

According to the NCERT context, the magnetic energy per unit volume is proportional to the square of the magnetic field strength, similar to the electrostatic energy in a capacitor. This is derived in equations (6.18) and (2.73).
