    54 We then need to add this contribution to the induction equation $\color{green}{-\nabla \times \mathbf{E'}}$ and the energy equation where it enters both the Poynting flux $-\color{green}{\nabla \cdot \left ( \mathbf{E'} \times \mathbf{B} \right)}$ and the work done on the the charge distribution $\color{green}{ - \mathbf{J} \cdot \mathbf{E'}}$.

    5656However the work done on the charge distribution would need to also be added to the thermal energy cancelling any changes in the total energy due to the $\color{green}{\mathbf{J} \cdot \mathbf{E}_{\scriptscriptstyle R}}$ term.  This leaves us with.
