# Electromagnetic Wave Equation

Hi,
We were told to show that the magnetic flux density B obeys a homogenous wave equation. This case applies to electromagnetic waves in a homogenous, linear, uncharged conductor.
Now I know that the wave equation for magnetic flux density is as follows.

[ tex ] \nabla^2-\epsilon\mju \frac {\deltaB} {\deltaT}=0 [ \ tex ]

However I am a little confused on what the solution of the wave equation will be for B. I have the solution for E and H and know they are both orthogonal how is B related to these?

There're two auxiliary equations that relate E and H to D and B via material properties. They have it in Wikipedia http://en.wikipedia.org/wiki/Maxwell's_equations [/URL]
