Multiple Choice

The magnetic fields generated in the rotor and stator of a motor cause the rotor to be pushed around the shaft.

Magnetic fields in a motor generate rotational motion by torque around the shaft axis, not by pushing the rotor along the shaft. The stator’s rotating magnetic field interacts with the rotor so that a tangential force acts to spin the rotor. This creates angular motion about the axis, while axial (along the shaft) forces are minimized or managed by bearings. So the statement describing the rotor being “pushed around the shaft” describes linear motion that isn’t how motor torque works, making it false.
