Question

What is the Maxwell's modification of ampere's law?

Answer 1

Maxwell's modification of ampere's law:

1. Maxwell used a symmetry consideration to modify Ampere's law.
2. A changing magnetic field induces an electric field, so a changing electric field must induce a magnetic field, according to Faraday's law. Because currents are commonly used to generate magnetic fields, a changing electric field must be associated with a current.
3. To satisfy the continuity equation of electric charge, Maxwell extended Ampere's law by introducing the displacement current into the electric current term.
