Which component in a generator is responsible for generating the magnetic field?

In a generator, the component responsible for generating the magnetic field is the rotor. The rotor is equipped with either electromagnets or permanent magnets that produce the magnetic field necessary for the generation of electrical energy. When the rotor spins within the generator, it interacts with the stator, where the coils of wire are located. This interaction induces a flow of electricity in the windings of the stator due to electromagnetic induction.

While the stator plays a crucial role by containing the windings where electricity is generated, it is the rotor that creates the magnetic field essential for this process. The windings are the conductive paths where the induced current is collected, while the commutator, found in some types of generators, is primarily used to switch the direction of current in the windings and does not generate the magnetic field itself. Thus, the rotor is the key component that creates the magnetic field necessary for the generator’s operation.
