An electric motor converts between these two types of energy.
What is electrical to motion (or mechanical)?
200
The name for a group of atoms with their magnetic poles pointing in the same direction.
What is a magnetic domain?
200
This is what two North poles will do when brought together.
What is repel?
200
This changes the voltage of an alternating current.
What is a transformer?
200
This is why an electromagnet has many practical uses.
What is because the magnetic field can be turned on or off.
200
Explain how you can demonstrate that magnetism is a force.
What is you can use a magnet to move objects!
300
This coverts electric energy to motion.
What is an electric motor?
300
Iron filings were used in class to show these.
What are magnetic field lines?
300
Explain how to make a basic electromagnet using household objects.
Objects: battery, wire, and a nail (or other iron object). Wrap the wire around the nail and then connect the wire to the battery.
300
An electric generator produces electricity by turning this within a strong magnetic field.
What is a wire coil?
300
This field extends into space.
What is the magnetosphere?
400
Uses induction to produce electric power.
What is an electric generator?
400
A force that can attract or repel objects.
What is magnetism?
400
When electrons move through a wire, a magnetic field is produced.
What is electromagnetism?
400
Just like electric charges, magnetic poles of opposite types will do this.
What is repel.
400
This allows us to tell directions because of the Earth’s magnetic north pole.
What is a compass.
500
The area around a magnet where the magnetic forces act.
What is the magnetic field?
500
Describe how an item can become magnetized.
An item can become magnetized with a strong magnet is held close to the material and each magnetic domain lines up with the magnet's field.
500
