Magnetism is a relativistic correction to the motion of electric charge. It is well understood at both the classical and quantum level.
The unification of quantum theory and special relativity is called quantum electrodynamics. It describes describes all phenomena involving electrically charged particles interacting by means of exchange by photons.
QED is the most accurate scientific theory ever produced in the history of mankind. While producing the theory was a team effort, a notable player was Richard Feynman, probably the most brilliant physicist of the 20th century and in many ways more deserving of fame than Einstein.

Well magnetism is 1 of the phenomena by which objects have an attractive or replusive force on other materials. Some objects that work with magnetism is iron, some steels, and the mineral lodestone. Magnetism forces arise from the movement of electrical charges. But Magnetism works like this example: two magnets push away because the magnets are in the same direction now if it was opposite like the bottom attracts to the top.

Magnetism is used in just about everything today. From finding direction to reproducing sound to generating electricity to imaging the human body, magnetism is ALL AROUND US. You can pretty much assume that anything electrical or mechanical uses magnetism in some fashion.

magnet - a body, as a piece of iron or steel, that possesses the property of attracting certain substances, as iron. By the way, you're using it now... Computers use magnetism to "remember" things. Computers are used in just about everything these days. Therefore, magnetism is very essential in our everyday lives. Good question...

Science does not yet know what causes magnetism. They can describe it and predict its action. Electricity cannot exist without a magnetic force being involved.
