Exploring Electricity and Magnetism

What is static electricity?

• Electricity that flows through wires

• Electricity that is stored in batteries

• Electricity that is generated by friction

• Electricity that powers appliances

Which of the following is a component of a simple electrical circuit?

• A magnet

• A resistor

• A switch

• A transformer

What is the main difference between an electromagnet and a regular magnet?

• An electromagnet is always magnetic

• A regular magnet can be turned on and off

• An electromagnet requires electricity to function

• A regular magnet is stronger than an electromagnet

What material is a good conductor of electricity?

• Rubber

• Glass

• Copper

• Wood

How can you determine if a material is an insulator?

• Checking if it allows the passage of electricity

• Checking if it blocks the flow of electricity

• Checking if it is magnetic

• Checking if it is heavy

Design a simple electrical circuit using a battery, a bulb, and wires. What is the role of the battery in this circuit?

• Provide light

• Conduct electricity

• Store electricity

• Supply energy

Explain how static electricity is different from the electricity used to light a lamp.

• Static electricity is generated by friction, while the electricity for the lamp flows through wires

• Static electricity is stronger than the electricity for the lamp

• Static electricity is used in homes, while the electricity for the lamp is not

• Static electricity is safer than the electricity for the lamp

Plan an investigation to test if a material is conductive. What is the first step?

• Connect the material to a battery and a light bulb

• Measure the weight of the material

• Check if the material is magnetic

• Observe the color of the material

Why is copper used in electrical wiring?

• It is a good insulator

• It is a good conductor

• It is lightweight

• It is magnetic

What happens when you bring a magnetic object close to a magnetic field?

• The object will repel the field

• The object will become magnetic

• The object will be attracted by the field

• The object will lose its magnetism
