... Yes, a charge creates an electric field at distances from the charge. Thus the field extends beyond the position of the charge itself to points where there is no charge present. No, a charge cannot experience force due to its own field because Coulomb’s law requires two charges to create equal and o ...

The main difference consists in change in magnetic flux linking the frame. In the first case, the magnetic ...

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.
