Please answer this physics II question!

You take a wire and wind it into a circular loop (leaving the two ends free so that they can be connected to a power supply). You take a longer wire and wind it around making 6 turns of about the same radius as your first single loop. If you run the same amount of current through both wires, compare the magnetic dipole moment magnitudes of the two setups. What is the ratio of the multi-loop current's dipole moment magnitude to that of the single loop current?

Explanation / Answer

magnetic dipole monent = N I A

for single loop:

dipole moment = I A

for multi-loop :

dipole moment = 6 IA

ratio = 6
