A long wire is along `x = 0, z = d` and carries current in positive y direction. Another wire is along `x = y, z = 0` and carries current in direction making acute angle with positive x direction. Both the wires have current I. Find the magnitude of magnetic induction at `(0, 0, 2d)`.

Along the direction of current carrying wire, the value of magnetic field is ?

Infinite wires, each carrying a current 0.5 A, are kept parallel to y-axis and intersecting x-axis at x=+-1 m, +02 m , +-4 m , +-8m etc. Wires kept at positive values of x carry current in the same direction while wires kept at negative values of x carry current successively in opposite directions as shown in Fig. A wire is kept parallel to x-axis and intersecting y-axis at y=2 m. It carries a current i. Assuming this wire to be insulated from others then the current i in it such that magnetic induction at O is zero is (assuming each wire to be infinitely long)
