The direction of a magnetic field travels from the _________ pole to the _________ pole.

• north; south

• south; north

• east; west

• west; east

• varies from north to south and south to north

At higher temperatures atoms of a magnetic material

• become more aligned

• become less aligned

• stay in the same alignment

• alignment when temperature increases depends mainly on the type of the magnetic material

Right-hand Rule

• to determine direction of a magnetic field from current flowing through a wire

• a coil of wire that acts as a magnet

• the coupling of a strong magnet inside an electrified wire coil

• dampener to decrease magnetic induction
