Electromagnet Flashcard

Front

What materials are needed to magnetize an object for electromagnetism?

Back

Iron or steel (e.g., a rod or nail) are needed to magnetize an object for electromagnetism.

Front

Do electromagnets require a power source?

Back

Yes, electromagnets need a power source to function.

Front

What surrounds every magnet?

Back

A magnetic field surrounds every magnet.

Front

What are the components of an electromagnet?

Back

The components of an electromagnet are a battery, copper wire, and an iron nail.

Front

What do electric currents produce?

Back

Electric currents produce magnetic fields.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

Front

How can you increase the strength of an electromagnet?

Back

You can increase the strength of an electromagnet by increasing the number of coils of wire or increasing the electric current.

Front

What is the role of the battery in an electromagnet?

Back

The battery provides the electric current needed to create a magnetic field in the electromagnet.

Front

What happens when the electric current is turned off in an electromagnet?

Back

When the electric current is turned off, the magnetic field disappears, and the electromagnet loses its magnetism.

Front

Can electromagnets be turned on and off?

Back

Yes, electromagnets can be turned on and off by controlling the electric current.
