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.
Spin causes electrons to exhibit magnetism.
Magnetism is mainly due to electrons, though some nuclei also have a magnetic moment.
There is no known role of magnetism in stellar evolution.

Electricity, magnetism and electricity are two aspects of a single force known as electromagnetism.

attract iron
This is known as paleomagnetism.
The known magnetism in a bar magnet is electromagnetism.
Electricity, magnetism and electricity are two aspects of a single force known as electromagnetism.
Repulsion from a known pole of a magnet is the ONLY valid test for magnetism.
Electricity, magnetism and electricity are two aspects of a single force known as electromagnetism.
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,.
