the torque exerted on a magnet or dipole when it is placed in a magnetic field 同义词：moment of a magnet,
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.
