Electricity is essential to our modern world. But over the years, public concern has arisen from confusing and sometimes conflicting research about the electric and magnetic fields in everyday life.
Electric and magnetic fields are invisible fields created by both natural and man-made sources. A natural source of EMF is the earth’s magnetic force field, while man-made sources include anything that conducts or consumes electricity — such as an alarm clock, refrigerator or power line. The strength of both electric and magnetic fields weaken quickly as you move away from the source, just like heat from a fire.
