Magnetism and Electricity Review 3

Front

What is magnetism?

Back

Magnetism is a force that can attract or repel certain materials, such as iron, and is produced by the motion of electric charges.

Front

What is electricity?

Back

Electricity is the flow of electric charge, typically through a conductor like a wire, and is used to power devices.

What is an electromagnet?

Back

An electromagnet is a type of magnet that is created by electric current flowing through a coil of wire, which can be turned on or off.

Front

What is a permanent magnet?

Back

A permanent magnet is a material that maintains a persistent magnetic field without the need for an external power source.

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to power the circuit.

Front

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow, consisting of a power source, wires, and a load (like a light bulb).

Front

What is a switch in a circuit?

Back

A switch is a device that can open or close a circuit, controlling the flow of electricity.

What happens when you fold paper between a magnet and a paper clip?

Back

Folding the paper several times can decrease the number of paper clips the magnet can pick up due to increased distance and material.

Front

What is the magnetic field?

Back

The magnetic field is the area around a magnet where magnetic forces can be detected and can affect other magnets or magnetic materials.

Front

How do magnets interact with each other?

Back

Magnets can attract or repel each other depending on the orientation of their poles: like poles repel, while opposite poles attract.
