Regarding ##I## as the electric current flowing in a wire:
##n## is the electron density, ##A## the cross sectional area of the wire, ##v## (or ##v_d##) the drift velocity of the electrons and ##q## (or ##e##) the charge of an electron.
See http://hyperphysics.phy-astr.gsu.edu/hbase/electric/miccur.html
