Consider two current carrying wires shown below. The current in the wire 1 is 4.5 A in the positive x direction. Find the magnitude and direction of the current in wire 2 if the net magnetic field at point A is to be 7.5 μT in the positive z direction (coming out of the paper).
additional information:the distance between wire 1 and wire is 25 cm and the distance between the wire 2 and point A is 12 cm.
