# Stator ring connection and coils question

Hello everyone:

I am trying to find a program or formula that will help me figure out how many windings, turns of coil, are needed per coil on a 6 coil steel stator ring powered by 3-phase AC power to get a certain magnetic field strength, about 1.3T. Is there any way that you could help me find out how many windings are needed per coil? Would I use the standard solenoid formula B=mu*N*L?

Could I use a standard ac plug with one hot leg and one neutral to power my steel stator ring coils, 6 total, to create a rotating magnetic field? If so, how would I connect the coils together and how would I connect those interconnections to the one hot leg and one neutral leg? And how would this affect the number of turns needed for each coil? Which would be better, Using a DC power supply or AC power from a plug with one hot leg and one neutral leg?
If DC is better to create the rotating magnetic field, how would I connect the six coils together and how would I connect those interconnections to a DC power supply

Thanks so much for the help.
