If a crane can pick up a car and then drop it, what might be on the end of the crane?
an electromagnet

What is a generator?
A machine that uses a magnet to make current electricity

Explain how a circuit works.
Electrons flow from the power source through the wires to the receiver and back into the power source.

Name the two types of circuits. Which one is better?
Series Circuit and Parallel Circuit- a parallel circuit is better because it will still work if one component is out because there are multiple pathways for the electricity to travel.

How does the static electricity machine work?
1. You spin the handle and start the flow of electrons because of the magnets rubbing against the wires. the electrons flow through the metal parts of the machine because they are conductors. When the electrons build up enough they "jump from one metal ball to the other creating a spark.

What is an object called that takes the magnetism from an magnet and becomes a magnet for while in the magnets magnetic field.
A temporary magnet

What are the three ways electromagnets are different than regular magnets?
The can be turned on and off, You can change the strength, you can change the direction of the current
