Front

What is an electromagnet?

Back

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

Front

How can you make an electromagnet stronger?

Back

You can make an electromagnet stronger by adding more coils of wire to the core.

Front

What happens when you reverse the poles of a magnet?

Back

Reversing the poles of a magnet changes the direction of the magnetic field, which can affect how it interacts with other magnets.

Front

What is the difference between a conductor and an insulator?

Back

A conductor allows electricity to flow easily (e.g., metals like copper), while an insulator does not allow electricity to flow easily (e.g., rubber, wood).

Front

What materials are good conductors of electricity?

Back

Good conductors of electricity include metals like copper, aluminum, and silver.

Front

What is a compass needle?

Back

A compass needle is a small magnet that aligns itself with the Earth's magnetic field, pointing towards the magnetic North.

Front

What is the role of a magnet in a compass?

Back

The magnet in a compass helps to determine direction by aligning with the Earth's magnetic field.

Front

What are the two poles of a magnet?

Back

The two poles of a magnet are the North Pole and the South Pole. Opposite poles attract each other, while like poles repel.

Front

What is magnetic attraction?

Back

Magnetic attraction is the force that pulls together opposite poles of magnets (North and South) or magnetic materials.

Front

What is magnetic repulsion?

Back

Magnetic repulsion is the force that pushes apart like poles of magnets (North and North or South and South).
