d)

a) Find the magnetic eld B at a distance R above the midpoint of a straight wire segment of length L carrying a current I. b) Find the magnetic eld at the center of a square of side L. c) Calculate the magnetic eld at the center of a regular polygon with to sides of length L. d) Rewrite the result found in c) as a function of the radius of the circle in which the nside regular polygon is inscribed. (Indicate the radius of this circle with (1.) Take the limit for n } 00 to nd the magnetic eld at the center of a circle
