How can a magnet be made?

• By cooling a piece of metal to a very low temperature

• By stroking a piece of metal with another magnet

• By placing a piece of metal in a strong magnetic field

• By heating a piece of metal to a high temperature

What is an electric circuit?

• A path that electricity flows through

• A device that converts electrical energy into other forms of energy

• A device that stores electrical energy

• A device that measures electrical current

What is a series circuit?

• A circuit where the components are connected in a series of branches

• A circuit where the components are connected in a series of loops

• A circuit where all the components are connected in parallel

• A circuit where all the components are connected in a single line

What is a parallel circuit?

• A circuit where all the components are connected in a single line

• A circuit where the components are connected in a series of branches

• A circuit where all the components are connected one after the other

• A circuit with a single path.

What is the advantage of a parallel circuit?

• The voltage is divided evenly among the components.

• If one component fails, the others will also fail.

• If one component fails, the others will still work.

• The current is divided evenly among the components.

What is the disadvantage of a series circuit?

• The current is not divided evenly among the components.

• If one component fails, the others will also fail.

• The voltage is not divided evenly among the components.

• The components cannot be replaced without breaking the circuit.

What is the property of magnets that allows them to attract objects towards them?

• Resistance

• Conductivity

• Magnetism

• Gravity
