... All magnets, whether permanent or electromagnetic, have two poles. Magnetic fields radiate from one pole then bends around to the other. The magnitude of the magnetic field decreases as the distance from the magnet increases. For the bar magnet, we can measure only the magnetic field outside it, for ...

If the current changes, the magnetic field changes, and so the flux changes giving rise to an induced emf. This phenomenon is called self-induction because it si the loop ...
