Magnetic Fields 1.5-2.2

Front

What happens when two magnets are brought close together and then let go?

Back

The magnets will move away from each other because the magnetic force will push the magnets apart.

Front

Why do opposite poles of magnets attract each other?

Back

Opposite poles attract because they create a magnetic field that pulls them together.

Front

What direction does the magnetic force move between the poles of a magnet?

Back

The magnetic force moves from the positive (north) pole to the negative (south) pole.

Front

What happens to two magnetic toy trains placed very close to each other?

Back

The trains will move away from each other because the magnetic force will push the trains apart.

Front

What is potential energy?

Back

Potential energy is the energy that is stored in an object or system.

Front

What are the two types of magnetic poles?

Back

The two types of magnetic poles are north and south.

Front

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

Back

Like poles repel each other.

Front

What is a magnetic field?

Back

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

Front

How can you visualize magnetic field lines?

Back

Magnetic field lines can be visualized as lines that emerge from the north pole and enter the south pole of a magnet.

Front

What is the relationship between electricity and magnetism?

Back

Electricity can create a magnetic field, and a changing magnetic field can induce an electric current.
