You have not mention direction of propagation.If the wave is propagation jn z direction then. B=z×x E/v=jE/v=jEosin(wt).where v is the velocity of propagation of the wave. You can use the formula k^×E=vB where k^ is a unit vector in the direction of propagation of wave.

since E = Bc so we can find b from here. also B = c(k^ × E ) use this formula
