A DC generator works on the principle of Faraday’s laws of electromagnetic induction.
Electromagnetic induction is the process where a conductor moving through a magnetic field (or a changing magnetic field near a conductor) induces an electromotive force (EMF), which can drive an electric current. Faraday’s laws quantify this phenomenon.
