Electric and magnetic fields, or EMF, are created by both natural and manmade sources, and occur all around us in our everyday lives. Electric fields are associated with the voltage or strength of an electrical source. Magnetic fields are present when current flows through various appliances, motors and conductors such as wiring and pipes. Together, these two fields are commonly referred to as EMF.
