Magnetic monopole

In particle physics a magnetic monopole is a hypothetical elementary particle that is an isolated magnet with only one magnetic pole a north pole without a south pole or vice versa 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 Magnetism
