Magnetic Dipole Moment

Magnetic Dipole Moment

Bar Magnet

Consider a bar magnet as given in the figure above, having magnetic strength -m and +m separated by a distance of 2l. From the figure, we can define magnetic dipole moment as:

Magnetic Dipole Moment is defined as the product of its pole strength and its magnetic length.

Mathematically,

M = m . 2l

M = Magnetic dipole moment

m = pole strength

2l = distance between two poles

SI unit  is Am²
