Question

Q2. (a) What are the prime information that we have from the Maxwell's equations? дв (b) Derive the modified version: VXE from the old version: VXE = 0 of the Faraday's at Law.

Answer 1

a)Oersted experiment predicts that elecetric current produces a magnetic field. faraday found from his experiment that a changing magnetic field produces an electric field. is the reverse true can a changing melectric field produces a magnetic field this answer is given by clerk maxwell. He states that magnetic field not only proces by electric current but also by a time varying electric field.He also pointed out that ampere's circuital law becomes consistent only if along with conduction current, there is an additional current called by him th displacement current.
