"EMF" or Electromagnetic Fields are composed of both electric and magnetic fields and occur naturally. The build-up of electric charges during thunderstorms (lightning) and the presence of the earth's magnetic field (static or DC) are examples. The electromagnetic spectrum also includes a range of EMF generated by humans. Power lines and electrical equipment emit extremely low frequency (ELF/AC) electromagnetic fields while higher frequency radio waves (RF) are generated by broadcast antennas, cell phone base stations, etc.
EMF causes electromagnetic interference or "EMI" with a large variety of sensitive equipment: DC magnetic fields from subway rail lines can disrupt computer monitor displays. ELF or AC magnetic fields from a building's electrical system can interfere with computer systems, monitors and special use equipment in hospitals, research labs, etc; RF from nearby broadcast antennas can interfere with wireless LAN systems, IT equipment and highly sensitive equipment in hospitals, laboratories, recording studios.
With the pervasive increase in EMF sources throughout the world, there is a corresponding increase in concern that human exposure to EMF may cause adverse health effects.
