Explain why it is necessary to use physical electric and magnetic fieldswhen determining the Poynting vector N
Question
Solution 1
The Poynting vector, denoted by N, is a fundamental concept in electromagnetism that represents the directional energy flux density of an electromagnetic field. It is named after its inventor, John Henry Poynting. The Poynting vector is defined as the cross product of the electric field (E) and the Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
