[QUOTE="Dale, post: 6428891, member: 43978"] No. There is no requirement that the B field be perpendicular to a wire. In the case you have described the field is perpendicular to the “passive” wire, but that is dictated by your setup and not the laws of EM. You don’t get substantial eddy currents in thin structures, you would need a sheet rather than a wire. In this case you will get some eddy currents and surface charges. This will block the E field of the wire and reduce the change in the B field. It will not block the B field per se, but just reduce its change. [/QUOTE]
