Lab 5.2 – Magnetic Fields Getting Started: Open the PhET
... D. Generator (Note: This is the FIFTH Tab) 1. Here you will find a water faucet, a compass, a bar magnet on a wheel (turbine), and a coil of wire connected to an incandescent bulb. Move the compass around a little and determine what it is reacting to at this time. ...

Magnetism - District 196
... Rules for Magnetic Field lines. 1. They show the shape of the field 2. They exit the North pole and enter the South Pole. 3. If the lines are close together the field is stronger. 4. The lines may never cross. 5. Use arrows to show the direction the north pole of a ...

... would always align itself so that it pointed approximately in the North/South direction on the Earth. We now know that this is because the Earth is a big magnet due to currents inside the Earth. Thus, people were using compasses for navigation long before we had any fundamental understanding of the ...

... Up until 1820, electricity and magnetism were thought to be two completely unrelated phenomena. Hans Christian Oersted accidentally found that a currentcarrying wire induces a magnetic field. Similarly, a magnetic field can induce a current in a wire moving through it. This “new” are of study ...

Hall Probes
... Photo: You can't see a magnetic field, but you can measure it with the Hall effect. What if you place a piece of current-carrying wire in a magnetic field and the wire can't move? What we describe as electricity is generally a flow of charged particles through crystalline (regular, solid) materials ...

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.
