Magnetic field intensity is defined as

A

Magnetic moment per unit volume

B

Magnetic induction force acting acting on a unit magneticpole

C

Number of lines of lines of force crossing per unit area

D

Number of lines of force crossing per volume

Text Solution

Verified by Experts

The correct Answer is:
B
Number of lines of lines of force passing through per unit area normally is intensity of magnetic field, hence option (c ) is incorrect. The correct option is (b).
