Question

faradays law states that the cmf induced is equal to the rate of change of flux in magnitude but maxwell equation says that from passing through closed surface is zero? explain

Answer 1

Faradays laws of induction states that the line integral of the electric field around any closed loop is equal to the negative of the rate of change of the magnetic flux passing through it. And according to Maxwell, the net magnetic flux coming out from any closed surface is zero and this statement relates to the sources of magnetic field. Any closed surface for a magnetic dipole, the magnetic flux is directed towards inward the south pole will be equal to the flux outward from the north pole. Therefore the net flux will always be zero for a given magnetic dipole. So, if there is a magnetic mono pole source then this will give a non-zero area integral.
