Electromagnetism
100
Any material that attracts iron.
What is a magnet?
100
A device which changes electrical energy into mechanical energy.
What is an electric motor?
100
A substance that is attracted to a magnet.
What is iron?
100
The interaction between electricity and magnetism.
What is electromagnetism?
200
The area around a magnet where magnetic forces act.
What is the magnetic field?
200
A device which is used to convert mechanical energy into electrical energy by electromagnetic induction.
What is a generator?
200
This is what the two ends of a magnet are know as.
What are the North and South poles?
200
What happens around ANY wire powered with electricity?
A magnetic field is generated.
300
The two ends of a magnet are called this.
What are poles or magnetic poles?
300
This is the effect of increasing the number of coils in a electromagnet?
What is "it will make the electromagnet stronger?
300
This is what happens when a magnets south and south poles are brought near each other.
What is "they will repel?
300
Why does a wire charged with electricity cause the needle of a compass to move? 
Moving electricity creates a magnetic field. This is called electromagnetic induction.
Moving magnets induce an electric current.
A moving electric current induces a magnetic field.
400
A force of attraction or repulsion between unlike or like poles.
What is a magnetic force?
400
This is how the Earth's magnetic field is similar to a magnet.
What is "both have North and South poles?
400
This is what happens when a magnets north and south poles are brought near each other.
What is "they will attract?
400
If sphere x is + and sphere y is -, how would you change the energy in their electric fields of attraction? 
bring them closer or farther apart from each other.
500
The strongest magnets in the world are made out of this.
What is Neodymium?
500
A temporary magnet created by coiling a wire around a metal core, and passing a current through the wire.
What is an electromagnet?
500
The parts of the magnet where the magnetic effects are the strongest.
What are the magnetic poles?
500
When the magnets are moving relative to the wire.
