Magnetic monopoles

... 2. When you add these together, they cancel, so the total flux must be zero! There is an escape from this conclusion however: the existence of a vector potential for a divergenceless vector field is only guaranteed in a region of space that has no holes in it. Since div B is not zero inside the mono ...

... Consider a system of N magnetic dipoles in an external magnetic field B and in temperature T. Each dipole has two states in the direction of the magnetic field: m, -m. a. Find the partition function, the average magnetization, the average energy, and the entropy b. Consider an isothermal process whe ...

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.
