SPH4U: Electric and Magnetic Fields
... The atoms and molecules in an insulator (ebonite, a plastic, is an insulator) hold their electrons close to the atoms. They do not allow them to freely move. When there is an electric interaction with another object, the valence electrons of the insulator can only shift around the atoms and don’t tr ...

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.
