Magnets & Magnetic Force

Front

What is a magnet?

Back

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

What is magnetic force?

Back

Magnetic force is the attraction or repulsion that arises between electrically charged particles due to their motion.

Front

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 wire coils around the core or increasing the electric current.

Front

What is a temporary magnet?

Back

A temporary magnet is a magnet that only retains its magnetic properties while in contact with a permanent magnet or when an electric current is applied.

Front

What is a permanent magnet?

Back

A permanent magnet is a magnet that maintains its magnetic properties without the need for an external power source.

Front

What are the north and south poles of a magnet?

Back

The north and south poles are the two ends of a magnet where the magnetic force is strongest.

Front

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.

Front

What materials are considered magnetic?

Back

Materials that are considered magnetic include iron, nickel, cobalt, and some alloys.

Front

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, affecting compass readings and protecting the planet from solar winds.
