U1L2: Electricity and Magnetism

What is the relationship between electricity and magnetism?

• They both come from charged particles called electrons.

• They are completely unrelated.

• Electricity is a type of magnetism.

• Magnetism is a type of electricity.

What happens when you touch a doorknob and feel a shock?

• Electrons jump through space between your finger and the knob.

• The doorknob is magnetized.

• The doorknob is electrically charged.

• Your body is magnetized.

How do power companies use wires in relation to electricity?

• To focus the flow of electrons.

• To create magnetic fields.

• To store electricity.

• To repel electrons.

What is the main difference between electricity and magnetism in terms of electron flow?

• In electricity, electrons flow from one place to another, while in magnetism, they do not.

• In magnetism, electrons flow from one place to another, while in electricity, they do not.

• Electrons flow in both electricity and magnetism.

• Electrons do not flow in either electricity or magnetism.

What happens when 'like' poles of magnets are placed near each other?

• They push each other apart.

• They attract each other.

• They create electricity.

• They create a magnetic field.

How do electromagnets in trains help them move?

• They repel each other, making the train float above the tracks.

• They attract each other, pulling the train along the tracks.

• They create electricity to power the train.

• They store energy for the train.

What is a circuit in the context of electricity?

• A closed loop that allows the flow of electricity to connect to itself.

• A device that stores electricity.

• A type of magnet.

• A wire that repels electrons.
