Question

Write the expression for the magnetic dipole moment of a current loop in vector form

Answer 1

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.
