Helical Electron Beams - F-J's Physics - Video 134

Описание к видео Helical Electron Beams - F-J's Physics - Video 134

Here I use the Teltron Electron Beam Tube to pass a beam of electrons almost parallel to a uniform magnetic field. The result is both very surprising and beautiful to look at. It is helpful in explaining the Northern Lights and why you get those swirling colours.
