The device used to produce electric current is known as a generator. An electric generator, also historically referred to as a dynamo, converts mechanical energy into electrical energy through the principle of electromagnetic induction [2]. This process involves a moving magnet or a rotating coil within a magnetic field to induce current. In contrast, an electric motor performs the reverse function, converting electrical energy into mechanical motion. Other devices mentioned serve different purposes: an ammeter is specifically designed to measure the magnitude of electric current flowing through a circuit [1], while a galvanometer is a sensitive instrument used primarily to detect and indicate the presence or direction of small electric currents [1]. Therefore, while motors consume current and meters measure it, only the generator is designed to produce it.
