When does static electricity occur?
When positive and negative charges no longer balance.

What is magnetism?
a force that acts on moving electric charge and magnetic materials that are near a magnet
100
What is an electromagnet?
a coil of wire with many loops through which an electric current passes
100
What is a materials that conducts electricity well?
Conductor

If Christmas lights ran on a series circuit and one burned out, what would happen to all of the lights on the tree?
The would all burn too
200
What is an example of how static electricity occurs?
Wearing slippers and running across the carpet
200
What happens to a magnet's poles if a magnet is broken into two parts?
each magnet will have its own north-seeking and south-seeking poles
200
What type of energy is produced when a coiled wire is spun around a magnet?
electrical energy
200
What is a material that conducts electricity poorly?
insulator
200
What type of circuits do most homes have?
Parallel circuits

Why does a compass needle point in a north-south direction?
The needle reacts to Earth's magnetic poles
300
Can you change an electromagnets strength?
Yes
300
What are good conductors?
copper, metal, etc
300
In what type of circuit does electricity flow, closed or open?
Closed
400
Do two positively charged particles attract or repel each other?
Repel
400
Who discovered that changing a magnetic field created an electric current in a wire?
Michael Faraday
400
How can the strength of an electromagnet be increased?
more turns in the metal coil
400
What are some examples of insulators?
blankets, hot pads, etc
400
What is a series circuit?
a circuit that doesn't let electricity continue to flow if one thing is broken
500
What are the building blocks of matter?
Atoms
500
What part of a magnet is the strongest?
The ends, at the poles
500
How does a switch on an electromagnet work?
The switch on an electromagnet controls the flow of electric current to it by opening or closing the circuit
500
Daily Double What is resistance?
the material does not allow electric charges to flow through it easily
500
What is a parallel circuit?
A parallel circuit allows energy to pass through even if one part of the circuit is broken
