Magnet therapy, or magnetic therapy, or magnotherapy is a form of alternative therapies medicine which involves magnetic fields effect. Professionals claim that subjecting certain parts of the body to doses of magnetic fields has a beneficial effect. This theory has led to the popularization of an industry involving the sale of magnetic-based products for "healing" purposes: magnetic bracelets; magnetic spectacles, wrists bands, ankles, and the back, shoe insoles, mattresses, and magnetic blankets (blankets with magnets woven into the material); and even water that has been "magnetized".

Magnet therapy involves the use of static magnetic fields made from permanent magnets and the electromagnetic therapy involves the application of electromagnetic waves to the patient. It is a form of cure under the magnetic effect.

The concept of magnetic therapy was also practiced centuries ago. In fact, there is a story which tells that Cleopatra wore magnetic jewellery for its healing powers. Several doctors have been practicing this technique since the 80’s and early 90s, the therapy went out of view for a considerable period. Presently, this therapy is gaining importance day by day and is becoming one of the important aspects of alternative medicines. The boom of the business helped the therapy gain popularity in developed nations like France, Japan, Germany, and USA particularly for its potential to heal soft-tissue injuries.
