## Main Question or Discussion Point

in electromagnetics , considering boundary conditions of dielectric and perfect conductor

, inside conductor E = 0. So, there should not be any time varying magnetic field. But in many books i have seen that inside conductor normal component of B is 0 because there is no time varying magnetic field. How ? But i say THERE can be a static magnetic field , so Bn can be non-zero.
