What would happen if the north ends of two magnets were close together?
What is repel?
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.
200
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.
200
What supplies current to an electrical circuit?
What is a battery (or other electrical source)?
200
What is a material that blocks an electric current from passing through?
What is an insulator?
200

An electric current will produce

What is a magnetic field?

300
True or False: All magnets have the same shape and size.
What is False?
300
If you rub your hair on a balloon and the balloon becomes negatively charged, what charge will your hair have?
What is a positive charge?
300

This is the measurement of the pressure of a circuit:

What is voltage?

300
Which of these materials is not a conductor: copper, aluminum, gold, or wood?
What is wood?
300

An electric current can be induced by a 

changing magnetic field.

400
True or False: All magnets have a north and south pole.
What is True?
400
An electrical circuit is made up of a connector (wire), a load (lightbulb), a switch, and a ____________.
What is a battery (or electrical source)?
400

This is a measurement of how fast particles are going through a circuit

Amperage, or current

400
Which of these materials is a conductor: rubber, glass, air, silver?
What is silver?
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?

500

What three things can you do to strengthen an electromagnet?

Increase current, more loops, better material of metal
