Answer to Question #178180 in Electricity and Magnetism for Vincent

Question

The maximum electric field in a plane electromagnetic wave is 600N/C. The wave is going in the 

x-direction and the electric field is in the y-direction. Find the maximum magnetic field in the wave 

and its direction.

Answer 1

Answer

The relationship between maximum electric field and magnetic field is given

$B_0=\frac{E_0}{c}=\frac{600}{3\times10^8}\\=2\times10^{-6}T$

We know direction of this magnetic field perpendicular to the given electric field.
