Hello,
1) The process is draw a line, go to create filed reports>>Geometry-polyline>>Quantity-Mag_B>>Done. Nothing is needed in field calculator unless you want to define the B at only one direction.
2)Please assign two motion bands.
3) You can run without excitation and use Moving.Force and the model radius to get the cogging torque.
