Magnetic torque
A current loop with area A and current I in a uniform magnetic field experiences no net magnetic force, but does experience a magnetic torque of magnitude The vector torque can be expressed in terms of the magnetic moment of the loop, as can the potential energy U of a magnetic moment in a magnetic field , B
A magnetic field exerts a force on a straight wire carrying current; it exerts a torque on a loop of wire carrying current. A magnetic field exerts a torque which tries to align the normal vector of a loop of current with the magnetic field. ...

The torque on the dipole is τ = µ×B, where B is the external magnetic field. The magnitude of this torque is µB sinθ, where θ is the angle between B and µ (that's just definition of cross-product).
Magnetism is one aspect of the combined electromagnetic force. It refers to physical phenomena arising from the force caused by magnets, objects that produce fields that attract or repel other objects.
