What is a filament?
You will have created 2 permanent magnets both with north and south poles.
What happens if you break a permanent magnet?
A continuous flow of electricity through a circuit allowing the components to work correctly.
What is a closed circuit?
The greater the number of loops, the stronger the total magnetic field is.
How can you make an electromagnet stronger?
The first source of an electric current.
What is a battery?
A temporary magnet produced by wrapping an electric wire around a steel rivet multiple times and letting electricity run through the wire.
What is an electromagnet?
Positive and Negative
What poles on a magnet are attracted to each other?

What are insulators?
Magnetic force is increased.
What happens when you increase the number of magnets being used together?
Energy source, connecting wires,and a lightbulb (or other working output sources)
What is required to complete an electric circuit?
Electromagnetism
What is the relationship between magnetism and electricity?
The balloon and your hair are given opposite charges and become attracted to each other.
What happens when you rub a balloon on your hair?
The type of material that conducts electricity poorly.
What are semiconductors?
The magnetic force becomes weaker.
What happens when you increase the space between magnets and what they are attracting?
A connected circuit where the switch has the working components turned off.
What is an open circuit?
The compass needle moves in response to the flow of electricity.
What proof do we have that electricity creates a magnetic field?
The bottoms of clouds build up negative charges, and the ground builds up positive charges.
