magnetic field A field of force that is generated by electric currents, or, equivalently, a region in which magnetic forces can be observed. Within a magnetic field a magnetic dipole may experience a torque and a moving charge may experience a force. A magnetic field with its associated electric field is called an electromagnetic field.
