An infinitely large flat surface has a surface density of electric charge. The surface moves with constant velocity in a parallel direction. Show that the differential version of the Poynting theorem holds at all points above and below the surface.
The magnetic flux density in all of space is given by
B=(3z)ax+(8x2−x2y)ay+(y+x2z)az Wb/m2.
