Derive the Poynting's Theorem
Answers
Answer:
The Poynting theorem should read rate of change of energy in the fields = negative of work done by the fields on the charged particles minus the Poynting vector term. ... The compensating change in momentum and energy would occur in the bodies holding the electric and magnetic fields.प
Answer:theorem is an energy balance: The rate of energy transfer (per unit volume) from a region of space equals the rate of work done on a charge distribution plus the energy flux leaving that region.
