Magnetism is one of the basic force in the nature.It keeps all things in this galaxy in order. Earth itself is a big magnet and its magnetic field is responsible for protecting all life on earth against harmful effects of high energy radiations.
Earth as a magnet has two poles, a North Pole and a South pole. These North and South poles are for navigational purpose only. In Biomagnetism the nomenclature is just opposite. The geographic North Pole is referred to as South pole and geographical South pole is referred to as North pole. It is because when a bar magnet is suspended South Pole is attracted to North Pole and vice versa.
Magnet therapy has two distinct areas; pulsed bioelectric magnetic therapy and fixed magnetic therapy. In simple words the fixed magnets emit a static magnetic field where as electromagnets emit pulsed magnetic fields. Both fixed magnets and electromagnets are two different sides of the same coin but the electromagnets have three sides – electric field, magnetic field and electromagnetic radiation (EMR) as compared to fixed magnets which have two sides – electric field and magnetic field. Electromagnetic radiation is the result of rapid acceleration and deceleration of the electrons.
