Magnetism Flashcard

Front

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.

Front

What are the two types of magnets?

Back

The two types of magnets are permanent magnets and temporary magnets.

Front

What is a permanent magnet?

Back

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

Front

What is a temporary magnet?

Back

A temporary magnet is a material that exhibits magnetic properties only when in the presence of a magnetic field.

Front

What are magnetic poles?

Back

Magnetic poles are the regions of a magnet where the magnetic force is strongest; every magnet has a north and a south pole.

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 is an electromagnet?

Back

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

Front

What materials are commonly used to make electromagnets?

Back

Common materials used to make electromagnets include copper wire and iron.

Front

What is the role of the battery in an electromagnet?

Back

The battery provides the electric current needed to create a magnetic field in the electromagnet.

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, increasing the current, or using a stronger core material.
