... A simple ac generator consists of a loop of wire rotating between the lines of force between the opposite poles of a magnet. The halves of each conductor loop travel through the magnetic lines of force in opposite directions, causing the electrons within the conductor to move in a given direction. T ...

Magnetic Field
... Magnetic Field of a Loop If you make a circular loop from a straight wire and run a current through the wire, the magnetic field will circle around each segment of the loop. The field lines inside the loop create a stronger magnetic field than those on the outside because they are closer ...

PHY 212 LAB – Magnetic Field As a Function of Current
... 1. Obtain a set of four neodymium magnets. We’ll treat this is a single magnetic dipole. 2. Use your compass to determine the N and S poles of your magnet. Place a large piece of Scotch tape on the N side of your magnet. (Note: I want no tape residue left on the magnets, so use a big piece that can ...

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.
