Physical Principles & Numerical Solution
In a DC generator, the coil rotates within a magnetic field, and the commutator is employed to convert the alternating current generated in the coil into direct current. The presence of the magnetic field, represented by the north (N) and south (S) poles, further confirms its identification as a DC generator.
