If $\vec{E}$ is an electric field and $\vec{B}$ is the magnetic induction then the energy flow per unit area per unit time in an electromagnetic field is given by |
$\vec{E} × \vec{B}$ $\vec{E}. \vec{B}$ $E^2 + B^2$ $\frac{E}{B}$ |
$\vec{E} × \vec{B}$ |
Direction of propagation is along Poynting vector which is given by $ \vec{S} = \vec{E} × \vec{B}$ |
