Natural Science Forum / Physics / Particle Physics / August 2007Electron with magnetic field
An Electron moving in a vacuum at a certain speed <> 0 creates a circular magnetic field around it. Does this mean the electron is losing (kinetic) energy? > An Electron moving in a vacuum at a certain speed <> 0 > creates a circular magnetic field around it. > Does this mean the electron is losing > (kinetic) energy? No. The energy needed to speed the electron up also goes into storing some energy in the magnetic field around it. Since there is no magnetic field "left behind" as the electron moves, then there is no change in the energy configuration and no energy leaking from the system. PD |
