Question

Poynting theorem relates the electric intensity e, magnetic intensity h to the rate of energy flow per unit area at a point p as

Answer 1

p = e × h
that is vector product of e and h

Answer 2

THE POYNTING THEOREM IS SHOWN IN THE FIGURE ATTACHED BELOW.

Explanation:

• The poynting theorem is analogous to the work-energy theorem.
• It states the law of conservation of energy.
• In this we consider a charge at time t, it produces an electric field, and a magnetic field.
• in this theorem
