Energy flow and the speed of electric field in DC circuit
... wire in the form of heat. So our "crazy" theory says that the electrons are getting their energy to generate heat because of the energy flowing into the wire from the field outside. Intuition would seem to tell us that the electrons get their energy from being pushed along the wire, so the energy sh ...

... needle with a diameter of just about 20 nanometers, a so-called vortex core. Because the vortex cores can project upward or downward from the two faces of the wafers, they are able, in principle, to store one bit. But there is a problem. “The needle can, indeed, be turned 180 degrees by an external ...

... results are given in Fig. 3 in paper by Zirin & Cameron (2002). From this figure it follows that values M 5247 and M 5250 correlate very closely in strength range M 5250 ≈ 1. So, there was no evidence of the dif−50 G < M < 100 G, and M 5247 /M ferences of 10–30%, which were discovered earlier by Ste ...

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.
