All magnets have two opposite sides, they are what?
Positive and Negative
100
What does the D-Cell battery do in a circuit?
Gives the circuit a source of energy
100
What is an electromagnet?
A magnet that has been strengthened with electricity
100
What metals are attracted to magnets
Steel, Iron, Nickel, and Cobalt
100

What does a switch do in a complete circuit?

 The switch will open and close the circuit.

200
All magnets have two poles, what are they?
North Pole and South Pole
200
What type of circuit is it when electricity can flow through, open or closed circuit?
Closed circuit
200
How can you increase the strength of an electromagnet?
Wrap the wire around the electromagnet more times, add more batteries, use a thicker wire
200
A positive side of a magnet would be attracted to what side of another magnet?
The negative side
200

What do the wires do in a complete circuit?

The wires provide a conductor (pathway) for the electricity to flow.

300

Which of the materials is a good conductor of electricity: plastic, rubber, wood, or metal?

Any type of metal
300

What type of circuit is it when electricity CANNOT flow through, and it is not working, open or closed circuit?

Open Circuit
300
Why is it important to have a switch for an electromagnet?
Electromagnets use a lot of energy and drain power sources quickly. It is helpful to be able to turn it on and off when you need it, and to drop materials.
300
When a magnet picks up a steel nail, and the nail picks up a paperclip, you turned the nail into a what?
Temporary magnet
300
If an item will allow electricity to flow through it is called what?
A conductor
400
Could you use a type of metal in a circuit instead of a wire to create a closed circuit?
Yes, metals conduct electricity, as long as you have positive and negative charges and a source of energy
400
What type of circuit is all lined up in a circle, so energy goes through step by step?
Series Circuit
400
What type of metal would you use in an electromagnet? Why?
Steel, Iron, Nickel, or Cobalt. They are attractive metals to magnets, and metals can all conduct electricity
400
What do we call it when two magnets stick together? 
Attract
400

If an item WILL NOT allow electricity to flow through it is called what?

An insulator
500
What do we call the type of drawing we make to show how the circuit is set up?
Schematic Diagram
500
What type of circuit can have energy flow out to 2 circuits at the same time?
Parallel Circuit
500
What type of electromagnet was used to send messages using a series of clicks and pauses?
Telegraph
500

What do we call it when two magnets push apart?

Repel
500
Why would light bulbs in a series circuit be more dim than in a parallel circuit?
Series circuits stretch the energy out and the lights have to share the energy so it is more dim
