The magnetic potential at a point 1m away from the centre of a short magnetic dipole of moment 50 `Am^(2)` along a line inclined to the dipole axis at`60^(@)` is

A

`2.5xx10^(-6)J//Am`

B

`5.2 xx10^(-6)J//Am`

C

`2.5xx10^(-5)J//Am`

D

`6.2xx10^(-5)J//Am`

Text Solution

Verified by Experts

The correct Answer is:
A
`V=(mu_(0))/(4(pi))(Mcostheta)/(r^(2))=(4pixx10^(-7)xx50xxcos60)/(4pixx1)`
`=2.5xx10^(-6)J//Am`
