The magnetic moment is the measure of how much an object reacts to a magnetic field. The magnetic moment of a current-carrying wire loop is area of the loop multiplied by the current in it. The magnetic force on an object is always proportional to its magnetic moment. The torque which aligns a magnet with a magnetic field is also proportional to the magnetic moment of the magnet.
