What is magnetism?

Back

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

What is a magnet?

Back

A magnet is an object that produces a magnetic field, attracting certain materials like iron, nickel, and cobalt.

What are the two poles of a magnet called?

Back

The two poles of a magnet are called the North Pole and the South Pole.

What happens when you cut a magnet in half?

Back

When you cut a magnet in half, each half becomes a new magnet with its own North and South poles.

What is an electromagnet?

Back

An electromagnet is a type of magnet in which the magnetic field is produced by an electric current.

Front

How can you increase the strength of an electromagnet?

Back

You can increase the strength of an electromagnet by increasing the number of coils of wire or increasing the electric current.

What is the Earth's magnetic field?

Back

The Earth's magnetic field is the magnetic field that extends from the Earth's interior out into space, created by the movement of molten iron in the outer core.

What is a coronal mass ejection?

Back

A coronal mass ejection is a significant release of plasma and magnetic field from the solar corona, often associated with solar flares.

What materials are attracted to magnets?

Back

Materials that are attracted to magnets include iron, nickel, cobalt, and some alloys.

What is the difference between permanent magnets and temporary magnets?

Back

Permanent magnets maintain their magnetism over time, while temporary magnets only exhibit magnetic properties when in a magnetic field.
