| Magnetic poles | regions where magnet's force is strongest -repel or attract |
| magnetosphere | area surrounding earth with a magnetic field |
| magnetic domain | region with a large number of aligned magnetic fields |
| ferromagnetic material | ex. Iron, nickel and cobalt |
| electromagnetic force | electricity and magnetism causing powerful electric charges |
| solenoids | coil of current-carrying wire that produces and magnifies a magnetic field |
| galvanometer | device for measuring small amount of current |
| If a magnet is held still under a coil | no current will be detected |
| if manets are moved quickly inside a coil | current will be detected |
