3. (5 pts) Fig. 5(a) shows a wire of length L carrying a current I and is bent into a circular coil of one turn. In Fig. 5(b) the same length of wire that has been bent into a coil of two turns. Assume B, and B, are magnitudes of magnetic field at the center of the two coils, and u, H, are the dipole moment magnitudes of the coil. What are the ratio (B/B. Hy/H)? (A)(1,1) (B)(2,1) (C)(2,1/2) (D)(4,1) (E)(4,2) (F)(4,1/2) (G)(8,1) (H)(8,2) (J)(8,1/2) and I Fig. 5(a) Fig. 5(b)
