Every permanent magnet has two of these.
What is poles....North and South
100
What is it called when you coil wire around a core and run an electrical current through the wire?
An electromagnet! Duh...it's the name of the category!

What are the 2 things needed to determine the speed of an object. 

Distance and Time 

100
Can you see magnetic fields?
No....they are invisible to the naked eye.
100
A light bulb converts electrical energy into ___________ and __________.
Light and heat.
200
When a permanent magnet "sticks" to another permanent magnet, we say they....
Attract
200
What is the difference between an electromagnet and a permanent magnet?
An electromagnet you can turn off. A permanent magnet you cannot turn off.
200

What would happen if you took one light bulb out of a series circuit that had a total of 3 light bulbs?

All light bulbs would go out.

200
Name one thing that would make a magnetic field.
A permanent magnet, electromagnet.
200
A fan converts electrical energy into ____________.
Motion or mechanical energy.
300
When a permanent magnet "does not stick" to another permanent magnet, we say they...
Repel
300
How do you make an electromagnet have a stronger magnetic field?
More coils of wire or more electricity (batteries).
300
What would happen if you took out one light bulb from a parallel circuit that had a total of 3 light bulbs?
The one you took out would obviously go out, whereas the other two would stay lit.
300

What is the needle in a compass attracted to?

The Earth's magnet...or magnetic field. North pole would be acceptable too.

300
A doorbell converts electrial energy into ___________.
Sound
400
When permanent magnets with similar poles come together, they will...
Repel each other.
400
How do you change the poles of an electromagnet?
Flip the battery so terminals are different.
400
What would happen if you took out two light bulbs in a parallel circuit that had a total of 3 light bulbs?
Two light bulbs would obviously go out, but the 3rd light bulb would stay lit.
400
What objects will make your compass give an incorrect reading?
Metal objects with iron/cobalt/nickel, permanent magnets, or anything that creates a magnetic field.
400
A photovoltaic cell (solar cell) converts light into ____________.
Electricity

When permanent magnets with opposite poles come together, we say they...
Attract to each other
