Extra Credit worth 5 points:  A square current loop, A, has a circular current loop, B, inscribed perfectly inside it.  Both loops have the same current.  If the magnetic field due to the square loop at the center point C is 9 μT, what is the magnetic field at C due to the circular loop?  Start from the Biot Savart law, show all steps, and select closest answer.
