ons of theequipotential suifaces by the plane of the figure. 264. Field due to Two Circular Currents.—Fig. 220 represents the lines of field and the equipotential surfaces forthe case of two equal and parallel circular currents with theirplanes at a distance equal to the radius Throughout a… … 265. Restriction to Theorem of Equivalence of Current and Shell.—In an important particular the field of a current isdifferent from that of a magnetic shell. We saw (191, ii.) that inpassing from any point close to a magnetic shell to an adjacent oneon the opposite side of it the potential changes…
