What statement is true concerning the use of commutating poles (also known as interpoles) in DC generators?

Question

Accepted Answer

These narrow poles are placed in the magnetic neutral plane between the main field poles and are designed to eliminate or reduce sparking caused by inductance of the armature coils.
