Implementation of new technologies and universal use of electricity led to emergence of artificial electromagnetic fields most of which often harmfully influence the person and the environment. This physical field arises where there are moving charges.
Nature of the electromagnetic field
The electromagnetic field represents a special type of matter. It arises around conductors on which electric charges move. Such force field consists of two independent fields – magnetic and electric which cannot exist in a separation one from another. Electric field at emergence and change steadily generates magnetic.
One of the first in the middle of the 19th century James Maxwell who possesses a merit of creation of the theory of the electromagnetic field began to investigate the nature of variation fields. The scientist showed that the electric charges moving with acceleration create electric field. Change generates it the field of magnetic forces.
The magnet if to set it in motion and also electric charge which hesitates or moves with acceleration can become a source of variation magnetic field. If the charge moves with a constant speed, then on the conductor the direct current of which constant magnetic field is characteristic flows. Extending in space, the electromagnetic field transfers energy which depends on current size in the conductor and frequencies of emitted waves.
Impact of the electromagnetic field on the person
Level of all electromagnetic radiations which create the technical systems designed by the person many times over exceeds the natural radiation of the planet. This field is characterized by thermal effect that can lead to overheating of body tissues and irreversible consequences. For example, long use of the mobile phone which is a radiation source can lead to temperature increase of a brain and a crystalline lens of an eye. The electromagnetic fields arising when using household appliances can become the reason of emergence of malignant new growths. In particular it belongs to a children's organism. Long finding of the person near a source of electromagnetic waves reduces overall performance of the immune system, leads to diseases of heart and vessels. Of course, completely it is impossible to refuse use of technical means which are a source of the electromagnetic field. But it is possible to take the simplest measures of prevention, for example, to use the cell phone only with the headset, not to leave cords of devices in electric sockets after use of the equipment. In life it is recommended to use the extenders and cables having protective shielding.
