What are ferromagnetic metals?

Back

Ferromagnetic metals are materials that can be magnetized and include iron, nickel, and cobalt.

What is a permanent magnet?

Back

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

Front

What creates magnetism?

Back

Magnetism is created by the movement of electrons, which generate magnetic fields.

Front

What are the two types of magnetic forces?

Back

The two types of magnetic forces are attractions and repulsions.

What happens when a magnet is brought near aluminum?

Back

Aluminum is not magnetic, so nothing will happen when a magnet is brought near it.

Front

What is the difference between a temporary magnet and a permanent magnet?

Back

A temporary magnet only retains its magnetism while in the presence of a magnetic field, while a permanent magnet retains its magnetism indefinitely.

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; like poles repel each other, while opposite poles attract.

Front

What is the role of electrons in magnetism?

Back

Electrons generate magnetic fields through their movement, and their alignment in materials determines the material's magnetic properties.

Front

What is magnetic attraction?

Back

Magnetic attraction is the force that pulls two magnetic objects towards each other.

Front

What is magnetic repulsion?

Back

Magnetic repulsion is the force that pushes two magnetic objects away from each other.
