Magnetics with polygon

A conducting wire of length LL is converted into a regular polygon of nn sides. On passing, a current of II through the wire produces a magnetic field of intensity BB at the center. Find the value of BB.

Details and Assumptions:

  • I=5A,L=2m,n=15.I = 5 A, L = 2 m, n = 15.
  • Give your answer in μT\mu T correct to two decimal places.
