I have a question about grounding/earthing. People are grounding themselves because EMF's of electrical appliances are adding a voltage difference to us and the earth. When someone grounds himself, the voltage difference immediately goes to zero. Electrons will flow to the body and these are beneficial to our health. What my question is: if I'm grounded to the earth and I'm near a strong EMF, will there be a constant current going through me? Because I'm being charged by the EMF and that charge is going to the earth, over and over again. I believe there isn't a constant current, because to have a current you need a difference in potential and there is not such thing, because I'm grounded to the earth. What do you think?
