What is static electricity?
100
The ends of a magnet. Can be north or south.
What are poles?
100
A magnet able to turn on and off when electricity is ran through a coil around a core.
What is an electromagnet?
100
An object that projects an invisible field that can move certain metals and effect them
What is a magnet
100
Wood, rubber, and plastic have a low "this"
What is conductivity
200
A batter provides what?
A constant flow of electrons, or electricity
200

200
Rubbing two objects together to induce an electric charge on one.
What is friction?
200
DAILY DOUBLE - worth 400
With electric charges and magnets, what to opposites do and like charges do?
opposites - attract
likes - repel
200
What is one way I can make a bulb brighter in a circuit?
add more batteries/remove some bulbs
300
What switch(es) need to be closed for the toaster to turn on?
D, C, and B - all
300
Where a magnet is the strognest.
What are the poles?
300
Which shows forces attracting and which shows forces repelling?
A - attraction
B - repelling
300
a measure of the amount of charge that moves past a
point in a certain amount of time (how fast electrons
move in a circuit)
what is voltage?
300
A balloon with a negative charge is hanging and a rod with a positive charge is brought near it. What happens?
The balloon and rod attract
400
The law that explains the following; like charges repel and opposite charges attract.
What is the Law of Electric Charges?
400
What would be the poles within the circles on the magnets?
left to right --> S, N, N
400
The field that the metal paper clip is within, causing it to float.
What is the magnetic feild
400
What we call the flow of electrons through a closed, wired system
What is a current?
400
Explain why the lightbulb is not lit
The circuit is not complete and electrons are not flowing
500
Which circuit is in parallel and which circuit is in a series?
left - parallel
right - series
500
What is the magnetic pole of the north pole, and how can you prove it.
The north pole has a southern polarity, because the north part of a magnet is attracted to it, but we call it the north pole because that is where the north points!
500
A good item to connect A and B would have a high what?
Conductivity.
500
TWO answers: the method of charging something with direct contact and the method of charging something without direct contact.
What is polarization (no contact) and conduction (contact)?

What is a statement you could make about metals with this image?
That not all metals are magnetic
