John Henry Poynting

John Henry Poynting was a British physicist known for his contributions to classical electromagnetism. He formulated the Poynting vector, which describes the transfer of energy in electromagnetic fields. This vector indicates the direction and magnitude of energy flow, helping to understand how electric and magnetic fields interact and propagate through space. His work laid the groundwork for advancements in electrical engineering, including the analysis of how energy travels in circuits and wireless communication. Essentially, Poynting’s contributions enhance our understanding of energy dynamics in systems influenced by electromagnetic fields.
