Problem 2) Find the magnitude and direction of the magnetic field B(z) at an arbitrary point along the z-axis due to the square loop of wire, of length w on the sides, located in the x-y plane centered on the origin, and carrying a counter-clockwise current I. [Hint: use the Biot-Savart Law and recall the result for a point P at a distance s from a straight segment of wire is B subtended by each half of the wire segment at point P.] = 4I sin 0, where 0 is the angle 2ns
