The peak electric field produced by the
Webb2 apr. 2016 · The electric field strength is related to the power of the laser by the Poynting vector. This is given by: S = E × H and the magnitude of S is the power. Assuming we can treat your laser as a plane wave (which seems reasonable) then E and H are at right angles so the power is simply: P = E H and H = E / η so we end up with: P = E 2 η WebbThe magnitude of the EMF produced in a generator depends on the speed at which the generator turns. True When I move a conductor through a magnetic field, the change in …
