... To calculate the magnitude of the emf (electromotive force), you must use Faraday’s Law of magnetic induction. For a single loop of a circuit, this may be expressed as: emf = -N[AB (cos ) ] t where N = number of loops in the circuit A= circuit loop area B = magnetic field normal to plane of loop I ...

Magnetic monopole
A magnetic monopole is a hypothetical elementary particle in particle physics that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). In more technical terms, a magnetic monopole would have a net ""magnetic charge"". Modern interest in the concept stems from particle theories, notably the grand unified and superstring theories, which predict their existence.Magnetism in bar magnets and electromagnets does not arise from magnetic monopoles. There is no conclusive experimental evidence that magnetic monopoles exist at all in our universe.Some condensed matter systems contain effective (non-isolated) magnetic monopole quasi-particles, or contain phenomena that are mathematically analogous to magnetic monopoles.
