This Demonstration shows the electric and magnetic field lines (in red and blue) of localized, timeÃ¢Â€Âdependent, finiteÃ¢Â€Âenergy, rational solutions (in , , , and ) of the sourceÃ¢Â€Âfree Maxwell equations that can be interpreted as classical (nonquantum) photons. For all times, any pair of electric and magnetic field lines is linked.
