Write the unit of magnetic dipole moment...

Write the unit of magnetic dipole moment.

A

`Am^(-2)`

B

`Am^(-1)`

C

`JT^(-1)`

D

`J^(-1) T`

Text Solution

Verified by Experts

The correct Answer is:
C
Torque `tau = m B sin theta`
`therefore m = (tau )/( B sin theta) therefore` Unit of `m= (J)/(T) = JT^(-1)`
