I forgot to mention that a vector field produces a "flux"
an integration of the vectors in a limited cross section
area and this result it is a scalar, indeed. This is the
case of magnetic flux[F-Wb] as an integration of magnetic
flux density[B-Wb/m^2].In this case you may consider the
current as integration of current density field in a
conductor cross section area. Then the "current" is
physically a "scalar" but ac current can be represented on
a paper as "phase-vector" as explained.
