EMF): Ordinary every day use of electricity produces magnetic and electric fields. These 60 Hertz fields (fields that go back and forth 60 times a second) are associated with electrical appliances, power lines and wiring in buildings.

A vector field of Electromagnetic energy. The Magnetic (H) and Electric (E) fields generated by any system of electric charges. A low current, high voltage, source will generate mainly an ELECTRIC FIELD. A high current, low voltage, source will generate mainly a MAGNETIC FIELD.

Electrical fields originating from the magnetic center of the earth.

(EMFs, also called electric and magnetic fields): Invisible lines of force that surround all electrical devices. The Earth also produces EMFs; electric fields are produced when there is thunderstorm activity, and magnetic fields are believed to be produced by electric currents flowing at the Earth's core.

Magnetism produced by electrical fields.

Energy fields that result from the existence and movement of electric charges. Electromagnetic fields occur naturally and can also be created.

a form of radiation produced by electrical power lines and appliances that may increase the risk of cancer
