Two long parallel wires are at a distance ` 2d` apart. They carry steady equal currents flowing out of the plane of the paper , as shown. The variation of the magnetic field `B` along the line `XX` is given by

Two long, straight, parallel wires are 1.00m apart (as shown in Fig). The upper wire carries a current I_1 of 6.00A into the plane of the paper. What is the magnitude of the net field at Q?

Let two long parallel wires, a distance d apart, carry equal currents I in the same direction. One wires at x=0 , the other at x=d (as shown in Fig) Determine magnetic field at any point x-axis between the wires as a function of x.
