The Natural Origins of Electromagnetic Fields

These are natural fields which do not belong to electromagnetic pollution.

The life on earth is all around, with and thanks to them organized. The electric field on the surface of the earth is due to the presence of electric loads in the high atmosphere.

Its most obvious demonstration is the flashes of lighting of a thunderstorm. The earth magnetic-field is produced by the molten currents of the magma in the nucleus of the earth and the electric currents which it generates. The earth magnetic-field leads the needle of the compass and gives precision upon the geographical position of the magnetic north pole.

We also find natural alternative fields, but their intensity is very weak and they change according to the solar activity, the atmospheric activity…

The living cells as well as our body and all the human beings generate electric currents and thus, electric and magnetic fields.

The electrocardiogram (ECG) measures electric currents in the heart and the magnetic field led by these currents.

In the brain, electric currents are measured by the electroencephalogram (EEG) and the led magnetic field induced by these currents.
