Electromagnets
100

Electricity is the flow of these.

Electrons

100
These materials allow the flow of electrons through them.
Conductors
100

This is a circuit with only one path for electrons to flow.

Series Circuit

100

Why does a compass "always point north"?

The compass is a magnet attracted to the magnetic south (geographic north) pole 

100

Name the three things we used to make an electromagnet.

Battery, wire, and nail

200

Give an example of static electricity in nature. 

lightning

200
Batteries are an example of this kind of current.
Direct Current (DC)
200

If a circuit is all wired correctly and the switch is open, is the light bulb on or off?

Off

200
Opposite poles of a magnet do this.
Attract
200

Give an example of an object that uses electromagnetism.

motor, generator, MRI, junkyard crane, headphones, speakers, fan motor, electric can opener, telephone, door bell, etc.

300

If an object has 9 positive charges and 8 negative charges, what is the overall charge?

positive

300
These materials prevent or stop the flow of electrons.
Insulators
300

A circuit with two or more paths for electrons to move through.

Parallel Circuit

300

If two magnets were brought together with the south poles facing each other what would happen?

Repel

300

How is an electromagnet different from a regular bar magnet?

Temporary:  on/off

400
This is created when electrons build up on the surface of an object.
Static Electricity
400

What are the required components to build a circuit?

battery, wire, load

400
If a light bulb is on, the circuit is complete and we call this an open or closed circuit?
Closed
400

True or False: When magnets are broken into smaller bits, the bits themselves become small magnets.

True

400

What uses electrical energy and converts it to rotational (mechanical) energy?

Electric Motor
500

Electricty travels at the speed of __________.

light

500
This is the unit used in the measurement of current (#of electrons)
Ampere or Amps
500
The force which moves electrons through a circuit.
Volts/voltage
500

Which direction do magnetic field lines point? (using the words toward/away and north/south)

Point towards south, away from north

500

What device converts rotational (mechanical energy) into electricity?

Electric Generator
