What is meant by 'magnetic dipole moment' of current loop? Write its SI unit.

Explanation

The product of current and area of the loop determines the magnetic dipole moment. Current in the loop generates a magnetic field. Hence the current loop acts as a magnet. The magnetic moment associated with the current loop is known as magnetic dipole moment.
`" "M=(I)(A)" "` where, 'A' - area of the current loop.
`" "M=pir^(2)I" "` where, 'r' - is the radius of the current loop.
