Front

What is the nature of the force between two magnetic objects when they are close?

Back

Attraction or repulsion.

Front

Which factor does NOT affect the strength of magnetic force?

Front

What type of charges produce a magnetic field when they are in motion?

Back

Electric charges.

Front

Where does the compass needle point in relation to Earth's magnetic field?

Back

Toward the south pole of Earth's magnetic field, located near the Earth's geographical north.

Front

What is the definition of magnetism?

Back

Magnetism is a physical phenomenon produced by the motion of electric charge, which results in attractive and repulsive forces between objects.

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 happens to the magnetic field when the electric current in an electromagnet is increased?

Back

The strength of the magnetic field increases.

Front

What is the role of a compass in navigation?

Back

A compass is used to determine direction by aligning itself with Earth's magnetic field.

Front

What is the difference between permanent magnets and electromagnets?

Back

Permanent magnets produce a constant magnetic field, while electromagnets produce a magnetic field only when an electric current flows.
