Solution
The function of the field winding in a DC machine is to produce magnetic flux. This is done by passing a current through the field winding which creates a magnetic field. This magnetic field then interacts with the armature winding to generate torque, which causes the rotor to turn. The strength of the magnetic field (and thus the torque and speed of the motor) can be controlled by varying the current in the field winding. So, the correct answer is d. To produce magnetic flux.
