Electric And Magnetic Fields

Electric and magnetic fields are invisible areas of energy often referred to as radiation that are associated with the use of electrical power and various forms of natural and man made lighting EMFs are typically characterized by wavelength or frequency into one of two radioactive categories.

Electric Current And Magnetic Fields

Magnetic Fields are produce by electric currents, which can be macroscopic currents in wire, or microscopic currents associated with electrons in atomic orbits.



Magnetic Fields sources are essentially dipolar in nature, having a north and south magnetic pole.
