Can changing electric filed produce magnetic field? What is displacement current? Explain electromagnetic waves and its properties. What are the uses of electromagnetic waves? Are electromagnetic waves transverse?
Electromagnetic waves (part-1)
Maxwell found an inconsistency in the Ampere’s law and suggested the existence of an additional current, called displacement current, to remove this inconsistency. This displacement current is due to time-varying electric field acts as a source of magnetic field in exactly the same way as conduction current.
