The healing power of a magnet can be employed for homeopathic use. These methods have been explained by Hahnemann in Materia Medica Pura under the North Pole and the South Pole of the powerful magnet bar. Though both poles have equal powers they do not oppose each other in their respective actions. While applying these magnetic fields to the patient, their power can be altered and modified by counting the duration of the application of the magnet to the patient.
The North Pole and the South Pole have distinctive curative effects. The adjustment and application of these poles can be done according to the symptoms produced by both poles. If any violent effect results due to over-application of the magnetic power, application of the polished zinc plate can be used as an antidote. Homeopathic materia medica contains medicines like “Magnetis polus australius (south pole of magnet)”, “Magnetis polus arcti (north pole of magnet)”, “magnetis poli ambo (magnet exposed to sugar of milk)” etc.
