Best Answer

Magnetism is not caused, it is one of the four known forces:

Strong nuclear force

Weak nuclear force

Electromagnetic force (magnetism)

Gravitational force

All matter has an electromagnetic force, the reason that we dont see objects stuck to each other, is that almost all matter on earth, has equal, positive, and negative polarity.

Understanding how a charge becomes positive, and negative, is very complex, and involves quantum mechanics.

What is a force that pulls magnetic materials across a distance?

Magnetism is a force that causes magnetic objects to move toward a magnetic force. The force is felt strongest on magnets which experience what is known as ferromagnetism, the strongest type of magnetism. When it is liquefied and cooled, oxygen can exhibit properties of magnetism. There are also non-magnetic substances that are not affected by a magnetic field or magnetism, these include plastics, gases, copper and aluminum,.
