Hello!
I' currently reading EM and am in need of a verification that I understood it correctly before proceeding. Just to see if I got this right:
The energy flowing out of a point, p, is described by the Poynting vector of the field at that point. The momentum density of the field is proportional to the Poyinting vector and therefore proportional to (i.e. has the same direction as) the energy flow from that point.
Please comment on this if you feel that I'm missing something or important information easily can be added.
Best Regards and Merry Christmas
