Electromagnetic Field Theory A plane wave magnetic field is represented by Bx = cos(y – ct). The electric and magnetic fields will be zero in the direction Ex = Ey = 0, Bx = By = 0. Ey = Ez = 0, By = Bz = 0. None of these. Ex = Ey = 0, By = Bz = 0. Ex = Ey = 0, Bx = By = 0. Ey = Ez = 0, By = Bz = 0. None of these. Ex = Ey = 0, By = Bz = 0. ANSWER DOWNLOAD EXAMIANS APP
