A flat circular coil, carrying a current, has a magnetic moment `mu`

A

`mu` has only magnitude it does not have direction.

B

The direction of `mu` is along the normal to the plane of the coil.

C

The direction of `mu` depends on the direction of the current flow.

D

The direction of `mu` does not if the current in the coil is reversed.
