Front

What is the Earth's magnetic field?

Back

The Earth's magnetic field is a magnetic field that extends from the Earth's interior out into space, affecting compass directions and navigation.

Front

What does a compass point to and why?

Back

A compass points north because of the Earth's magnetic field.

What happens to the force on a paper clip when the distance from a magnet decreases?

Back

The force on a paper clip increases when the distance from a magnet decreases.

Front

What is a field in physics?

Back

A field is an area around an object that can exert forces on other objects without them touching.

Front

What is a magnetic field?

Back

A magnetic field is the area around a magnet where it can attract or repel other magnetic materials.

Front

What creates electric fields?

Back

Electric fields are created by static electric charges.

Front

What is the relationship between distance and magnetic force?

Back

As the distance between a magnet and an object decreases, the magnetic force increases.

Front

What are the two types of electric charges?

Back

The two types of electric charges are positive and negative.

Front

What is the effect of a magnetic field on a compass?

Back

A magnetic field causes a compass needle to align itself with the direction of the field.

Front

What is the difference between static and moving electric charges?

Back

Static electric charges are stationary, while moving electric charges create electric currents.
