100
any material that attracts iron or things made of iron
What is a magnet
100
This forms when charged particles from the sun hit oxygen an nitogen atoms in the air. The atoms become excited an then give off light of many colors
What is an aurora
100
this machine uses electro-magnetic induction to change mechanical energy into electrical energy
What is an electric generator
100
generators in power plants make this type of current
What is alternating
100
the source in nuclear power plants is this type of energy
What is thermal
200
points on a magnet that have opposite magnetic qualities
What are the magnetic poles
200
this machine measures current or voltage
What is a galvanometer
200
we can use energy from any one of these to turn turbines and generate electricity
What is rushing water, wind, coal, or gas
200
generators contain a coil of wire attached to a rod that is free to do this
What is rotate
200
this type of transformer increases voltage and decreases current

300
A needle on a compass
What is a magnet
300
a device that changes electrical energy into mechanical energy
What is an electric motor
300
a device made up of two coils of wire wrapped around an iron ring that is used to increase or decrease the voltage of alternating current

500
this ding dong machine uses magnetism to work
What is a doorbell
500
If you bring an electric current near a compass needle, the needle will do this
What is move
500
high voltage in your home is generally not this
