Two factors that determine the amount of torque produced by a direct current motor are the strength of the magnetic field of the pole pieces and the ____.
A) strength of the magnetic field of the armature
B) direction of the magnetic field
C) direction of the turning force
D) strength of the magnetic lines of flux

Question

Quizplus · Accepted Answer

The strength of the magnetic field of the pole pieces determines the strength of the magnetic field that interacts with the armature, which in turn determines the amount of torque produced by the motor. The direction of the magnetic field and the direction of the turning force do not directly affect the amount of torque produced. The strength of the magnetic lines of flux is essentially the same as the strength of the magnetic field, so answer D is not a distinct factor.
