Question

define magnetic moment of a bar magnet

Answer 1

a magnetic moment of a bar magnet is a vector quantity that is a measure of the torque exerted on a magnetic system (such as a bar magnet or dipole) when placed in a magnetic field and that for a magnet is the product of the distance between its poles and the strength of either pole.

Answer 2

Answer:

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