Figure a shows a length of wire carrying a current i and bent into a circular coil

Question:

Figure a shows a length of wire carrying a current i and bent into a circular coil of one turn. In Figure b the same length of wire has been bent to give a coil of two turns, each of half the original radius.

(a) If Ba and Bb, are the magnitudes of the magnetic fields at the centers of the two coils, what is the ratio B b/B a?

(b) What is the μ b/μ a of the dipole moment magnitudes of the coils?
