Expert Answer
The magnetic dipole moment of the current loop is equal to the product of ampere-turns and area of current loop. It is denoted by M.
M = nIA
Where, n = number of turns in a circular current loop.
I = current through the loop.
A = area of each turn of the loop.
Magnetic dipole moment is a vector quantity. Its direction is perpendicular to the plane of loop outwards for anticlockwise current in loop and is directed inwards for clockwise current in loop.
