Answer to Question #93871 in Electricity and Magnetism for Umar

Question

Details on Working principles of generator and electric motor

Answer 1

The principle of operation of the generator is based on the phenomenon of electromagnetic induction, when an EMF appears in a conductor moving in a magnetic field and crossing the lines of the magnetic induction vector, therefore, such a conductor can be considered as a source of electrical energy.

The moving electric charges that create an electric current in a magnetic field are affected by the Lorentz force, which tends to shift the charges in a plane perpendicular to the direction of the current and the lines of magnetic induction. When an electric current passes through a metal conductor or a coil made of it, this force tends to move / rotate each turn with current and the entire coil as a whole. Thus, the energy of the current is converted into the energy of mechanical motion.
