Fundamentals - Electro-Magnetic Radiation (EMR)

E- and H-fields
Electro-Magnetic Radiation is a term used to designate artificially generated electromagnetic pollution, meaning electric (E) fields and magnetic (H) fields.

Such fields arise wherever there is a voltage or a current. All types of radio broadcasting and TV transmitters produce electromagnetic fields, and they also arise in industry, business and the home, where they affect us even if our sense organs perceive nothing.

Unit of electric field strength: Volts per meter (V/m)

Units of magnetic field strength: Amperes per meter (A/m) or magnetic flux density (B) in Tesla (T) or Gauss (G)
