Making the Generator 2D model into a Motor 2D model

Hello all,

How would one change the example model, "Generator 2D" into a motor? Is there a way to make the rps parameter of the "Prescribed Rotational Velocity" property be based on the magnetic field created by the coils using something like rmm.Bx?

How would I make it so that it is the magnetic fields that create the rotation instead of just the prescribed rotational velocity? I know in the Rotating Machinery 3D tutorial the eddy currents created in the copper creates the rotation, is there something similar I could do using a 2D model?

Thank you guys so much for any help.
