What is the difference between magnetic moment, magnetic dipole moment and orbital magnetic moment?
The magnetic moment of a magnet is a quantity that determines the force that the magnet can exert on electric currents and the torque that a magnetic field will exert on it. A loop of electric current, a bar magnet, an electron, a molecule, and a planet all have magnetic moments.
Dipole Magnetic Moment: A vector quantity associated with the magnetic properties of electric current loops or, more generally, magnets. It is equal to the amount of current flowing through the loop multiplied by the area encompassed by the loop, and its direction is established by the right hand rule for rotations. It can be thought of as a vector pointing from the south to the north of a magnetic dipole, and is then equal to the length of the dipole times the strength of either of its poles. Also called magnetic moment.
The magnetic moment associated created due to the spinning of electrons is known as the orbital magnetic moment.
