Title: Electromagnetic energy density and poynting vector of a relativistic oscillator
Type of Resource: Animação/simulação
Objective: Observe the electromagnetic behavior of a relativistic oscillator
Abstract: The electromagnetic energy density and Poynting vector of a moving charge are computed by the Heaviside-Feynman formulas. The amplitude a(in meters) of the oscillator acos(ωu)in the x direction with the frequency ω(measured in hertz) describes the moving charge in the xy plane at z=0 . The z component of the Poynting vector, the electric energy density, and the magnetic energy density of the oscillator are computed for an xy region at arbitrary height z .The observation time point is when the charge is crossing the coordinate origin with negative velocity aω. The speed of the charge varies from small values to the speed of light, and the Demonstration displays the resulting changes in the electromagnetic energy density and Poynting vector
