Maxwell’s Equations of the Electromagnetic Field Theory

Maxwell’s Equations of the Electromagnetic Field Theory. Gauss’s Law – charg e makes an electric field. The magnetic field is solenoidal (no monopole sources). Faraday’s Law of electromagnetic induction -- E curls around a changing B . Ampère’s Law – current makes a magnetic field.
