Solution to problem 2
... as Σ B · dn = 0 (thanks to the Stokes’ theorem), which means that the net flux of the magnetic field through any closed surface Σ is always zero; in other words, H there are no!magnetic monopoles. The second one, ∇ × E + ∂t B = 0, is the Faraday’s law of induction, in the integral form, ∂Σ E · dl = ...

... A long straight wire of radius R carries a current I that is uniformly distributed over the circular cross section of the wire. Find the magnetic field both outside the wire and inside the wire. Let’s look at the INSIDE field, ri < R We first need to identify exactly what is the ENCLOSED current. It ...

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.
