(a) Find the magnetic field at the centre of a square loop, which carries a steady current I. Let R be the distance from the centre to the side. (b) find the field at the centre of a regular n-sided polygon, carrying a steady current I. Again, let R be the distance from the centre to any side. (c) Check that your formula reduces to the field at the centre of a circular loop, in the limit  

Two circular coils of radius R, each with N turns, are perpendicular to a common axis. The coil centers are a distance R apart. Each coil carries a steady current I in the same direction as shown in Figure P29.38. (a) Show that the magnetic field on the axis at a distance x from the center of one coil is
