magnetic field
... Electrons (and other particles) have an intrinsic property called spin that also contributes to their magnetic moment. The electron is not physically spinning. It has an intrinsic angular momentum as if it were spinning. Spin angular momentum is actually a relativistic effect ...

... Oersted discovered that there was a relationship between electricity and magnetism. Thanks to Oersted and a few others, by using electricity, we can now make huge magnets. We can also cause them to release their objects. Electricity and magnetism are closely related. The movement of electrons causes ...

modelling of magnetic fields generated by cone
... illustrated in Fig. 1. Hereunder, the following examples are concerned with models of one or two cone-shaped coils equipped with/without magnetic yokes. The coils are mounted over the welding electrode with vertically oriented axes of symmetry. This model has been solved by FEM [5] for a 2-D field s ...

Superconducting magnet
A superconducting magnet is an electromagnet made from coils of superconducting wire. They must be cooled to cryogenic temperatures during operation. In its superconducting state the wire can conduct much larger electric currents than ordinary wire, creating intense magnetic fields. Superconducting magnets can produce greater magnetic fields than all but the strongest electromagnets and can be cheaper to operate because no energy is dissipated as heat in the windings. They are used in MRI machines in hospitals, and in scientific equipment such as NMR spectrometers, mass spectrometers and particle accelerators.
