In what way does this happen? Would that mean a time dependent E field would produce a case in which the divergence of B is not 0. Surely for a closed surface this would not be possible? In the question itself, the E field mentioned is only dependent on position so a time dependent case is...

Homework Statement Using the divergence theorem, evaluate the total flux of a magnetic field B(r) across the surface S enclosing a finite, connected volume of space V, and discuss its possible dependence on the presence of an electric field E(r). Homework Equations ∇.B=0 The...

So the potential of the middle plate is equal to the potential difference of the first region plus the potential difference of the second region? I guess this is because both of the plates are contributing to the field and not just the one plate. For the question regarding the adding of n...

Electrostatics -- 3rd plate inserted into parallel plate capacitor Homework Statement This question is from the book by I.S Grant and W.R Phillips on Electromagnetism. Two large parallel plates of area A and distance d apart are maintained at potentials 0 and V. A third similar plate...
