Magnetic Forces

Front

What happens to the potential energy when a magnet is moved closer to another magnet?

Back

The potential energy increases.

Front

What do magnetic force field lines indicate when they show attraction?

Back

They indicate an attractive force by opposite poles.

Front

Can objects be affected by magnetic force without touching?

Back

False, objects do not need to touch to be affected by magnetic force.

Front

What happens to potential energy when a magnetic object is moved away from a magnet?

Back

The potential energy increases because the object moves against the magnetic force.

Front

What is a magnetic field?

Back

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

Front

What is the relationship between like poles of magnets?

Back

Like poles repel each other.

Front

What is the relationship between opposite poles of magnets?

Back

Opposite poles attract each other.

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

What is magnetic force?

Back

Magnetic force is the attraction or repulsion that arises between charged particles due to their motion.

Front

What is the effect of distance on magnetic force?

Back

The magnetic force decreases as the distance between magnets increases.
