Electricity... step by step

What are the basic concepts to keep in mind when considering the effects of electricity on health?

Why are we mainly interested in magnetic fields?

The magnetic field crosses through the human body, whereas the electric field only partly penetrates it (it is roughly reduced by a one million factor between the outside and the inside of the body ; it mainly causes the migration of electric charges (ions) towards the surface of the body).

Due to this characteristic, the magnetic field is thought to have health effects. Nonetheless, some researchers think that the effects of electric fields on organisms should not be ignored.

Having established a basic electrical vocabulary, the time has come to take a guided tour in our environment to determine our EMF exposure. Well... here goes!
