# A fiat circular coil, carrying a current, has a magnetic moment μthe direction of μ is along the normal to the plane of the coilμ has only magnitude; it does not have directionthe direction of μ depends on the direction of the current flowthe direction of μ does not change if the current in the coil is reversed

A
the direction of μ is along the normal to the plane of the coil
B
the direction of μ depends on the direction of the current flow
C
the direction of μ does not change if the current in the coil is reversed
D
μ has only magnitude; it does not have direction
Solution
Verified by Toppr

#### The area vector →A is upward if the current in the loop is anti-clockwise and downward if the current in the loop is clockwise.
