Magnetism

Front

What is magnetism?

Back

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

Front

What causes magnetism?

Back

Magnetism is caused by the motion of electric charges, particularly the movement of electrons.

Front

What is an electron?

Back

An electron is a subatomic particle with a negative charge that orbits the nucleus of an atom and contributes to electric current.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit in which components are connected end-to-end, so that the current flows through each component in turn.

Front

What happens if a switch in a series circuit is open?

Back

If a switch in a series circuit is open, the circuit is incomplete, and the current cannot flow, causing any connected devices (like bulbs) to be off.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where components are connected across common points or junctions, allowing multiple pathways for current to flow.

Front

What is an insulator?

Back

An insulator is a material that does not allow the easy flow of electric current, preventing the movement of electrons.

Front

What is a conductor?

Back

A conductor is a material that allows the easy flow of electric current, facilitating the movement of electrons.

Front

What is the role of protons in magnetism?

Back

Protons are positively charged particles in the nucleus of an atom, but they do not directly cause magnetism; it is primarily the motion of electrons that creates magnetic fields.

Front

What is the difference between attraction and repulsion in magnetism?

Back

Attraction occurs when opposite poles of magnets come together, while repulsion occurs when like poles of magnets push away from each other.
