What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. It consists of a wire wound into a coil, often wrapped around a core material like iron.

What happens when you rub a needle on a magnet?

Back

The needle becomes a magnet.

Front

What components do you need to build an electromagnet?

Back

You need a wire, a rivet (or iron core), a battery, and a switch.

Front

What is Morse code?

Back

Morse code is a method of encoding text characters as sequences of dots and dashes, used in telecommunication.

Front

What is the purpose of a switch in an electromagnet circuit?

Back

A switch controls the flow of electricity in the circuit, allowing you to turn the electromagnet on or off.

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, components are connected end-to-end, so the current flows through each component one after another. In a parallel circuit, components are connected across common points, allowing current to flow through multiple paths.

Front

What materials can be used to create a magnet?

Back

Materials like iron, nickel, and cobalt can be magnetized to create permanent magnets.

How does a compass work?

Back

A compass works by using a small magnet that aligns itself with the Earth's magnetic field, pointing towards magnetic north.
