  Currently only three spatial and one temporal dimensions are considered to be
"physical". Recently, solutions to a plethora of questions have used the notion
of extra-dimensions. The experimental verification of the existence of such
extra dimensions, however, remains elusive. Here by applying standard
electromagnetism to five dimensional Minkowski space-time, we propose a novel
test ground to search for a new non-compactified lengthlike extra dimension. in
this regard, we propose superconductors as a testbed for this hypothetical new
extra dimension.
