What Is Magnetic Moment Of A Bar Magnet?

The magnetic moment is defined as a vector relating the aligning torque on the object from an externally applied magnetic field to the field vector itself.

The relationship is given by:

τ = μ * B


τ is the torque acting on the dipole

B is the external magnetic field

μ is the magnetic moment.

The magnetic moment is a quantity that determines the torque it will experience in an external magnetic field.
