The dimension of (angular momentum/ magnetic moment) are `[MA^(-1) T^(-1)].` is it correct?

Answer

Yes

Explanation

Angular momentum ` = I omega = [M^1L^2 T^(-1)]`
Magnetic moment = Current `xx`area
` = [A L^2]`
`("Angular momentum")/("Magnetic moment") = ([M^1 L^2 T^(-1)])/([AL^2])`
` = [M^1A^(-1)T^(-1)]`
The relation in correct.
