In this problem, there are three reluctance's in the right hand side path S3, S4 and Sg connected in series and they are in parallel with the middle path of reluctance S2. These two parallel paths are connected to S1 and source of AT (ampere-turn) in series.

Our first job is to find the total flux of source and the net reluctance of the circuit. These two parameters will give the value of mmf of the coil and in turn the current in the coil.
