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).
