100
An electric charge in motion.
What is an electric current?
100
Electricity needs this in order to flow.
What is a circuit?
100
Happens when opposite charges are brought together.
What is they attract?
100
The force that pushes or pulls magnetic items near a magnet.
What is magnetism?
100
A coil of wire wrapped around an iron core.
What is an electromagnet?
200
An electric charge can flow in only one path.
What is a series circuit?
200
There aren't any breaks in this type of circuit.
What is a closed circuit?
200
Happens when objects with the same charge are brought together.
What is they repel?
200
The invisible field surrounding magnets.
What is a magnetic field?
200
True/False: All magnets have a south-seeking pole and a north-seeking pole.
What is true?
300
Has two or more paths for electric charges to take.
What is a parallel circuit?
300
This must be true of a circuit in order for electricity to flow.
What is it must be closed?
300
Electricity does not flow very easily through these.
What are insulators?
300
The direction that one end of a compass needle will always point.
What is north?
300
True/False: The magnetic field will not become charged after coils are wrapped around a magnet and the power source is turned on.
What is false?
400
Created by a break in a circuit.
What is an open circuit?
400
An open circuit would do this to a flow of charges.
What is stop the flow of charges?
400
True/False: The electric field is strongest further away from the charged object.
What is false?
400
This can change the direction of a compass needle.
What is the pull of a close by magnet?
400
This is the shape of a magnetic field.
What is the same shape as the magnet itself?
500
The material does not allow electric charges to flow easily.
What is resistance?
500
This is what the circuit must be composed of in order for charges to flow.
What is a conductor?
500
This causes static electricity.
What is positive and negative charges no longer balance?
500
The reason why a compass needle points north/south.
What is the needle is drawn to the pull of Earth's magnetic north pole?
500
Three ways you can make an electromagnet stronger.
What are add more coils, use a larger iron core/magnet, and use a more powerful power source (battery, etc.)?
