A planar electromagnetic wave is propagating in the -x direction. At a certain point P and at a given instant, the electric field of the wave is given by E = (1.27 V/m)ĵ. What is the magnitude and direction of the magnetic field vector of the wave (in nT) at the point P at that instant? Denote the +z direction as positive, and the -z direction as negative. (Use c = 2.9979 × 108 m/s) nT
