100

Electricity is the movement of these:

What are negatively charged particles?

100
Is a circuit open or closed if you haven't turned on the switch?
What is open?
100
What is a material that lets electric current pass through?
What is a conductor?
100
True or False: An electromagnet is a permanent magnet.
What is False? An electromagnet can be turned on or off. Once the circuit is broken, the magnetism is lost.

If a south end of a magnet is close to a north end of a magnet, the magnets will _________.
What is attract?
200
True or False: Like charges attract and unlike charges repel.
What is False? Like charges repel and unlike charges attract.

400

This rule is used to determine the relationship between current and magnetic field

What is the right hand rule?
500

These are sections of a material that have individual magnetic fields and can be aligned by a magnet

What are domains?

500
Naturally-occurring electricity that occurs when there is a buildup of negative charges in one place. 
What is static electricity?
500

Where does the current of a circuit start?

At the plus (or high potential) side.

500

Insulators have a high amount of this, while conductors have a low amount

What is resistance?
