The amount of work done in carrying a unit N-pole from infinity to a point against the magnetic field is

A

Magnetic induction

B

Magnetic potential

C

Magnetic moment

D

Magnetic torque

Text Solution

Verified by Experts

The correct Answer is:
B
`v=(mu_(0))/(4pi) (Mcostheta)/(r^(2))=(mu_(0))/(4pi) (M)/(r^(3))=(10^(-7)xx216)/(6xx10^(-2))^(3)=0.1T.`
