2. Four long parallel current carrying wires arranged in a square of side (s). The currents have different directions as shown but are all the same magnitude I Find a general symbolic expression for the magnetic field (expressed in ijk notation) at the center of the right side of the square expressed at the point P shown. (a) Explain in words diagram(s) and equation(s) your method of solving this problem. Include how you will use the symmetry of the problem to simplify the solution. (b) Draw a large labeled diagram that clearly shows all the magnetic field vectors at the point P. Do a symbolic solution showing all your algebra and a simplified answer in terms of po, I and s.
