Every magnet has a north and south pole, just like the earth. Opposite poles attract - so the north pole attracts the south pole and the south pole attracts the north pole. So if you place two north poles together or two south poles together they will push each other away. A magnet's strength is strongest at the poles and weakest in the middle. The theory behind magnet therapy is that the magnetic fields produced by magnets can penetrate the human body and affect the functioning of individual cells and improve the working of the nervous system and various organs. Others claim that magnets increase blood flow to an area, boosting the flow of oxygen and other nutrients, and ultimately reducing pain.
