What are magnetic field lines?

Back

Magnetic field lines are imaginary lines that represent the direction and strength of a magnetic field.

What is an electric circuit?

Back

An electric circuit is a closed loop that allows electric current to flow, consisting of a power source, conductors, and a load.

Front

What is the role of a switch in a circuit?

Back

A switch controls the flow of electricity in a circuit by opening (breaking the circuit) or closing (completing the circuit) it.

Front

What particles flow through an electric circuit?

Back

Electrons flow through an electric circuit, carrying electric charge.

Front

What is gravity?

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is magnetism?

Back

Magnetism is a physical phenomenon produced by the motion of electric charge, resulting in attractive and repulsive forces between objects.
