Question

A fiat circular coil, carrying a current, has a magnetic moment $μ$

This question has multiple correct options

A

$μ$ has only magnitude; it does not have direction

B

the direction of $μ$ is along the normal to the plane of the coil

C

the direction of $μ$ depends on the direction of the current flow

D

the direction of $μ$ does not change if the current in the coil is reversed
