Is Current a Scaler or Vector Quantity?

There is a bit of a problem here. Your teacher may have been only thinking of the value of a current flowing in a wire as read on an ammeter. In that case current is just a scaler number.
However the wire in which the current flows has a direction. Any magnetic field associated with the current will have a direction related to the Biot-Savart Law:
Here, dl is a vector element pointing the direction of a wire element. So in this sense current is indeed a vector quantitiy.
