Predicting performance of a motor using electrical theory?

Hi the question is "a dc motor has been constructed using one pole pair having a square surface of 6cm x 6cm and produces a flux of 18mWb. The commutator has 4 segments which allows for two simple loops to be connected, two brushes are used with the positive applied to the brush nearest the south pole passing a current of 15A." Predict the performance of the motor by reference to electrical theory.







as for Relevant equations I am not sure maybe lenz's law?







To begin with I thought about using lenz's law but I need a little guidance.



Thanks
