Figure shows an end view of two long, parallel wires perpendicular to the xy plane, each carrying a current I, but in opposite directions.

Graph the magnitude of `vecB` at point on the x-axis.

Figure shows an end view of two long, parallel wires perpendicular to the xy plane, each carrying a current I, but in opposite directions. At what value of x, the magnitude of vecB is maxismum?
