Week 8 Homework 1 Serway 20.1 Physics 1B
... An emf is caused by a change in flux, which can be produced by a change in magnetic field strength, magnetic field direction, or area perpendicular to the magnetic field. Since the magnetic field in this problem is constant (not changing in magnitude or direction), an emf can only be produced by cha ...

Electrical Currents - NRG Gladstone Power Station
... A current that flows continuously in one direction is called a ‘Direct Current’ (DC). An example of a direct current is the electricity supplied by batteries. Electricity always flows in a circuit. We can compare it to water flowing through a pipe. If you stopped the flow with a plug at the end of t ...

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.
