The magnetic moment has dimensions of

A

`[LA]`

B

`[L^(2)A]`

C

`[LT^(-1)A]`

D

`[L^(2)T^(-1)A]`

Text Solution

Verified by Experts

The correct Answer is:
b
Magnetic moment of a current carrying coul is definet as the product of current in the cell with the are of unit in vector from That is
`overset(vec)(M) = 1 overset(vec)(r) A`
Thus, dimensions of `[M] = [A] [L^(2)]`
`= [L^(2)A]`
