Amplify Magnetic Fields Review (ch 1 and 2)

Front

What is potential energy?

Back

The energy that is stored in an object or system.

Front

What happens to the potential energy if you move magnet 2 toward magnet 1?

Back

The potential energy increases because Magnet 2 moves against the magnetic force.

Front

What do magnetic field lines indicate about two magnets?

Back

If the field lines are pointing away from each other, the magnets will repel.

Front

What happens to two sets of magnets if their field lines indicate attraction and repulsion?

Back

Set 1 magnets will repel, set 2 magnets will attract.

Front

What will happen when two magnetic toy trains are placed next to each other?

Back

The trains will move closer to each other.

Front

What is a magnetic field?

Back

A region around a magnet where magnetic forces can be felt.

Front

What is the relationship between magnetic field lines and the strength of a magnetic field?

Back

The closer the lines are, the stronger the magnetic field.

Front

What is the effect of distance on the strength of a magnetic field?

Back

The strength of the magnetic field decreases as the distance from the magnet increases.

Front

What is the principle of magnetic attraction?

Back

Opposite poles of magnets attract each other, while like poles repel.

Front

How can you determine the direction of a magnetic field?

Back

By using a compass, which aligns itself with the magnetic field lines.
