Where do electromagnets get their power?

An electrical source (usually a battery)

An electromagnet has a north and south pole, but what determines if the pole is north or south?

The charge on the end of the battery

The magnet will alternatively change between north an south poles

An electromagnet does not have north or south poles

How many batteries are connected

How does the number of coils affect the strength of an electromagnet? Choose all that apply.

Increasing the coils increases the strength of the magnet

Decreasing the coils increases the strength of the magnet

How does the core material affect the strength of an electromagnet?

The core must be iron for the electromagnet to work properly.

The core material has not effect on the strength of the magnet.

The core can be made of any material and it will work

The core can be made of any metal and it will work.

How does increasing the electric current affect the strength of an electromagnet? Choose all that apply.

Increasing the electric currect increases the strength of the magnet

Increasing the electric current decreases the strength of the magnet

How does the type of wire material affect the strength of an electromagnet?

Electromagnets can only be made using copper wire.

The type of wire material has no effect on an electromagnet. Electromagnets can be made using any material.

Electromagnets can be made using any type of wire, however, aluminum wire works the best.

The type of wire has no effect, but the power source matters.

The strength of a magnet can be affected by

The type of material to make the magnet

Using copper instead of iron to make the magnet

The strength of a magnet cannot be affected by anything

If you have two opposite magnetic poles facing each other, what will happen?

The magnets will be attracted to each other

The magnets will repel each other

The magnets will not interact with each other

Magnets that are arranged like this will _______.

move towards each other (attract)

move away from each other (repel)

These magnets will _______.

move away from each other (repel)

move toward each other (attract)

This is a picture of a simple electromagnet. How can the electromagnet be made stronger?

Add more coils of wire to the nail.

Reverse the poles of the magnet.

Remove all the coils and the nail.

Amy used a magnet to hold one piece of paper on the refrigerator. Later, she tried to use the same magnet to hold a stack of four pieces of paper, and the magnet wouldn't stick to the fridge. Why did this happen?

The magnet couldn't hold due to the thickness of the paper

A magnet isn't attracted to the refrigerator.

Which is NOT a use of magnets?

Storing information on computer hard drives.

How is a permanent magnet DIFFERENT from a temporary magnet?

A permanent magnet keeps its magnetism for a long time.

A permanent magnet attracts materials made of iron.

A permanent magnet has a magnetic field.

What is an electromagnet?

a temporary magnet made from current carrying wire around a magnetic metal core.

a permanent magnet with a north and south pole
