Corrigendum: Intrinsic symmetry of Ampère’s circuital law and other educational issues

Ref.: Can. J. Phys. 90, 67 (2012).

In a recent paper [1], Anacleto et al. illustrated the concept of displacement current from an educational perspective using a conducting wire segment connecting two opposite charges. We have just become aware that this same problem had previously been addressed by Charitat and Graner [2]. We regret that we were unaware of ref. 2 at the time of writing our paper and fully acknowledge Charitat and Graner’s [2] priority in originally analyzing the aforementioned illustrative example.
