Biot-Savart Law

A square loop of wire, of side L, carries a current I. a) Determine the magnetic field B at points on a line perpendicular to the plane of the square which passes through the center of the square. Express B as a function of x, the distance along the line from the center of the square. b) For x >> L, does the square appear to b ...continues
