What are electromagnetic fields of electricity?


The electric and magnetic fields (EMF ´ s) are invisible lines of force associated with:

  • the production
  • the transmission
  • and the use of electric power

What are the main sources of electromagnetic fields.


The main sources of electric and magnetic fields are:
  • high voltage transmission lines
  • secondary power lines
  • power transformers
  • and facilities and lighting appliances in buildings.

The electric and magnetic fields are also caused by motors and circuits that are in electronic equipment and devices.

What are the components of the electromagnetic fields?


An EMF is an energy field created by electrically charged objects.
An electromagnetic field has two "components", a magnetic component and an electricalcomponent. The electric field is produced by stationary loads, and the magnetic field by moving charges (currents).

Electromagnetic fields are also referred to as
"Electromagnetic Radiation" (EMR).

Cannot see, feel or hear the electromagnetic fields, are outside of the visible light, but are part of the electromagnetic spectrum.
