What components are needed to build a simple electromagnet?

Back

To build a simple electromagnet, you need a wire, a conductor (like a nail), a battery, and some paper clips.

Front

What happens when you reverse the poles of an electromagnet?

Back

Reversing the poles of an electromagnet changes the direction of the magnetic field.

What is the difference between a permanent magnet and an electromagnet?

Back

A permanent magnet produces a constant magnetic field, while an electromagnet can be turned on and off.

Front

How can you make an electromagnet stronger?

Back

You can make an electromagnet stronger by adding more wire coils and/or batteries.

Front

What is the role of the wire in an electromagnet?

Back

The wire conducts electricity, which creates a magnetic field when current flows through it.

Front

What is a magnetic field?

Back

A magnetic field is the area around a magnet where magnetic forces can be detected.
