Amplify Magnetic Fields Mid-unit Flashcard

Front

What is an electromagnet?

Back

A type of magnet in which the magnetic field is produced by an electric current.

Front

What do the letters N and S represent in magnets?

Back

The magnetic poles of a magnet.

Front

What happens when two like poles of magnets are brought close together?

Back

They will move away from each other because the magnetic force pushes them apart.

Front

What happens when two opposite poles of magnets are brought close together?

Back

They will move closer to each other because the magnetic force pulls them together.

Front

What is potential energy in the context of magnets?

Back

The stored energy in a system due to the position of the magnets relative to each other.

Front

What happens to potential energy when a magnet is moved against the magnetic force?

Back

The potential energy increases.

Front

What happens to potential energy when a magnet is moved in the same direction as the magnetic force?

Back

The potential energy decreases.

Front

What is the effect of distance on the magnetic force between two magnets?

Back

The magnetic force decreases as the distance between the magnets increases.

Front

What is the role of magnetic poles in magnetism?

Back

Magnetic poles determine the direction of the magnetic force and how magnets interact with each other.

Front

How can you create a stronger electromagnet?

Back

By increasing the electric current or adding more coils of wire.
