ALNICO
A material made from Aluminum, Nickel, and Cobalt- magnetism retained for a long time
MagLev

Poles
Ends of the magnets (end of any magnetic field) NORTH AND SOUTH
Magnetic + Geographic poles
Magnetic north- geographic south, magnetic south- geographic north
Electromagnets
A magnet created by electricity, only works when surrounded by electric field
Induced Magnetism
Magnetism that only occurs in the presence of a magnetic field
Induced current
A current caused by magnetism- no battery- only works when in magnetic field
Generator
Machine that makes electricity through magnetism
Motor
Machine that makes magnetism made from electricity
