Problem 2. a) Two long parallel wires a distance w apart each carry current 1/2. Find magnetic field, B, at a point distance, d, from one wire, in the plane of the wires. b) A long, very thin, rectangular conducting sheet of width w carry a total current I. Find magnetic field, B, at a point distance, d, from the edge of the sheet, in the plane of the sheet. c) What are the limiting equations for B in parts a and b when w goes to zero? Calculate them!
