... There are many analogies between electrostatics and magnetostatics (time independent magnetic fields). Just as there are two types of electric charge, there are two types of magnetic “charge”. They are called the North pole “N” and the south pole “S”. Magnetic field lines come out of north poles and ...

Magnetic Force on Moving Charges
... An important property of the magnetic force is that it depends on the velocity of the charge In other words, the magnetic force is non-zero only if a change is in motion This property of the magnetic force is not shared by the gravitational force and the electric force Those forces are independent o ...

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.
