Magnetic field-a space around a magnet where the magnetic force is active.
Magnetic Domain-a group of atoms with their magnetic fields pointing in the same direction.
Aurora-the light given off from the sun’s charged particles crashing into atoms in the Earth’s atmosphere.

- uses magnets to convert motion energy to electricityhttp://sustainableconsciousnessnetwork.wordpress.com/
Power Plants contain Electric Generators, machines that use a magnetic field to turn motion into electricity
Transformer- a machine that changes the voltage of an alternating current without losing much energy.
A magnet floats above a superconductor
Particle accelerators use superconductors to get particles up to nearly the speed of light,
