Application/occurrence
Static and low frequency electric and magnetic fields are all around us in many forms everyday: for instance, static fields come from tramways or high voltage direct current (HVDC) transmission, and low-frequency fields are associated with electrical appliances, power lines and the railway grid. Anti-theft devices in department stores and supermarkets sometimes use low frequency fields. Magnetic resonance tomography (MRT) in medicine is based on strong static magnetic fields, among others. Electric cars or hybrid vehicles, of which the driving systems also create low frequency electric and magnetic fields, will play an important role in the future. The so called magnet-based remedies are rare applications.
