We need to understand the concept of scalar and vector in the right sense to get this cleared. For a scalar, the magnitude doesn't change with direction whereas for a vector, the magnitude changes with direction, and that is the reason we need to specify the direction along with magnitude for a vecto...

Current is not a scalar quantity....its a tensor quantity as its direction is fixed. Current density is current per unit area and as area is a vector quantity so is the current density.

when you add current it doesn't follow laws of vector addition,so it is a scalar but current density is the cuurent flowing normally through the area, so direction is applicable,hence a vector
