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 materials are typically attracted to magnets?

Back

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

Front

What happens when two unlike poles of magnets are brought together?

Back

They attract each other.

What happens when two like poles of magnets are brought together?

Back

They repel each other.

Front

What is the magnetic field?

Back

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

Front

How does distance affect the strength of a magnetic force?

Back

The strength of a magnetic force decreases as the distance between the magnet and the object increases.

Front

What is static electricity?

Back

Static electricity is the accumulation of electric charge on the surface of objects.

Front

What causes static electricity?

Back

Static electricity is caused by the transfer of electrons between materials, often through friction.

Front

What is the principle of attraction and repulsion in magnets?

Back

Opposite poles attract each other, while like poles repel each other.

Front

What is an electromagnet?

Back

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