Electromagnetic fields (EMF) are present everywhere in our environment.There are natural and man-made EMF fields and they exist everywhere on Earth. The human eye cannot “see” them, but the body can at times feel where they are present. Wherever there is an electric charge, there is an electric field. Thunderstorms create natural electromagnetic fields.
Electromagnetic waves have been more and more often exploited in many technologies. It has boomed in recent years without the general public taking much notice. These technological waves create electromagnetic fields originating from human activity.
