Describe two methods for increasing the torque produced by a single conducting loop in a direct-current motor.
What will be an ideal response?
The amount of torque, or turning force, developed by this single loop is directly dependent on the strengths of the field flux and the conductor flux. To strengthen the field flux, it is customary to use electromagnets for the field poles of a motor. To strengthen the conductor flux, the current in the wire must be increased.
