... OK. We’ve seen how electricity can produce magnetism, so now let’s turn it around. If moving electric charges can produce magnetism, could a magnetic field be used to make charges move? That’s exactly what Michael Faraday wanted to do. In 1822, he wrote a goal in his notebook: “Convert magnetism int ...

... around the [010] axis, a relatively large expansion of the a-axis and relatively small change in the length of the c-axis are observed. Figure 2 shows the pseudocubic lattice parameters as a function of the Y-content, defined as apc = a⁄√2, bpc = b⁄2, cpc = c⁄√2, where a, b and c are the lattice par ...

... Just like Gauss’ Law, Ampere’s Law provides the simplest method for determining the magnetic field of a known current distribution … but it can only be used in a practical way if the problem has enough symmetry. It all boils down to choosing a suitable Amperian loop. The mathematical curve we choose ...

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.
