While a parallel-plate capacitor is being charged, Ampère’s law in its original form predicts different magnetic fields depending on whether the chosen surface passes through the wires or between the plates. Which addition to Ampère’s law resolves this inconsistency?
(a) Including the term dtdQ as an additional current through the gap
(b) Introducing a time-varying magnetic flux term dtdΦB to the law
(c) Including the term ϵ0dtdΦE as an effective current through the gap
(d) Adding the surface charge density σ explicitly to Ampère’s law
