Physical Science - Magnetism Flashcard

Front

What is a compass needle?

Back

A compass needle is a small magnet that aligns itself with the Earth's magnetic field, indicating the direction of magnetic north.

Front

What are magnetic domains?

Back

Magnetic domains are regions within a magnet where the magnetic fields of atoms are aligned in the same direction.

Front

What is a magnetic pole?

Back

A magnetic pole is one of the two ends of a magnet where the magnetic field is strongest, typically referred to as the north and south poles.

Front

What happens when electricity runs through a wire?

Back

When electricity runs through a wire, it generates a magnetic field around the wire.

Front

What is a temporary magnet?

Back

A temporary magnet is a material that becomes magnetized when in contact with a magnet but loses its magnetism when removed from the magnetic field.

Front

What is magnetism?

Back

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

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

What is the relationship between electricity and magnetism?

Back

Electricity and magnetism are interrelated; a changing electric field can produce a magnetic field and vice versa.

Front

What is a magnetic field?

Back

A magnetic field is the region around a magnet where magnetic forces can be observed.

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 needles and navigation.
