Many thanks to mfb. I wonder if the water drop levitating (orbiting) effect of Kelvin Generator can be the example of magnetic field formation by mechanically moving charge. Otherwise it is so strange... Please have a look at the videos. Kelvin dropper experiment is easy to set up. The reason...

Thank you mfb. Could you give me any reference that measures magnetic field of electron beam? I see only articles of electron beam deflected by magnetic field. By the way, I found this article. http://educate-yourself.org/cn/ElectronBeamMagneticField.pdf This says that magnetic field is not due...

Hi! I wonder if there was any experimental measurement of magnetic field produced by mechanically moving charges. In principle the equation is well known. (1) But is there any experimental proof of this equation? I know it can be reformulated into this. (2) My question is "Is there any...

In the meanwhile I found out the best document available in the internet. http://74.63.154.231/here/wp-content/uploads/2013/06/Chevalier_electrical_surface_potential-2007.pdf I am reading it carefully. What I already learned ist that * the reason for the negative charge of the Earth surface...

Yes, I read and answered 10% is cloud to ground. I just read in wikipedia. But this cloud to ground discharge (normal lightning) cannot be understood, thinking that the Earth surface is negatively charged. As I read, lightning from positive cloud to negative Earth is rare. Sorry for the...

Thank you for being active in the discussion. 10% of lightning is cloud to ground. This energy should be equal to 600 MW according to the quote. This means the total energy (causing lightning) in the cloud is around 6 GW. It is still far from 16 TW unless we change the claim that 10% of...

Thank you Dave. It am more confused by reading the quote. 1. I thought 2000A of eath vertical electricity is due to ion coming down, not electrons leaving the earth. 2. From my internet search, lightning dissipates average 16 TW, which is 140,000 TWh per year. It is much more than 600 MW. 3...

I am trying to understand why is the surface of the Earth negative. From the internet search, I found -105 C. I make a sequence according to the conventional model and question at each step. 1. The surface is slightly negative: here I just accept and start. 2. Atmosphere is positive: Some...
