Maxwell''s displacement current was postulated in part III of his 1861 paper ''On Physical Lines of Force''. Few topics in modern physics have caused as much confusion and misunderstanding as that of displacement current. This is in part due to the fact that Maxwell used a sea of molecular vortices in his derivation, while modern textbooks operate on the basis that displacement current can exist in free space. Maxwell''s derivation is unrelated to the modern day derivation for displac…
