... • The total charge inside the Gauss surface should be zero from Gauss’ law and E=0 on this surface. Therefore there must be a charge –q distributed on the surface of the cavity. • The similar argument can be used for the case where the conductor originally had a charge qC. In this case the total cha ...

Thus, building both line charges runs over the same angular range as building the semicircle, so we may consider the lines together. Now we need to write down the field contributions dE and dE0 from ...

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.
