Explain the basic principles of electro -magnetism and how electric motor works
Electromagnetism is the physical force that results from the interaction of electrically charged particles. This force is responsible for the creation of magnetic fields and the movement of electric charges.
The basic principle of electromagnetism states that when an electric current flows through a conductor, it creates a magnetic field around it. This phenomenon is utilized in electric motors, where the interaction between magnetic fields and electric currents causes the motor to generate mechanical motion.
Electric motors consist of two main components: a stator and a rotor. The stator is the stationary part of the motor and contains coils of wire that are connected to an external power source. When an electric current flows through these coils, it creates a magnetic field.
The rotor, on the other hand, is the rotating part of the motor and is equipped with magnets or coils of wire. These magnets or coils interact with the magnetic field generated by the stator and cause the rotor to spin. This spinning motion is what produces mechanical work in electric motors.
In summary, the basic principle of how an electric motor works is by utilizing the electromagnetic force generated by the interaction between magnetic fields and electric currents to produce mechanical motion.
