Electromagnetic Induction Name Institution Abstract Electromagnetic induction is a principle, which predicts the behaviour of the electric currents whenever they interact with the magnetic field in the production of the electromotive force. It is a basic principle of operation for many types of electric devices such as motors.
Introduction Electromagnetic induction involves the electric current produced across a conductor that moves in a magnetic field. It is the basic operation for transformers, generators, electric motors, induction motors, solenoids, and synchronous motors. Electromagnetic induction is the process, which gives a prediction of the behaviour of the interaction between electric current and the magnetic field. Michael Faraday discovered the concept of induction in the year 1831. He stated that the produced electromotive force (emf) around a path that is closed is directly proportional to the magnetic flux rate of change through a surface that is path bounded. This implies that, there would be some induced electric current in a closed circuit whenever the flux going through a conductor bounded surface changes. This means that the conductor will be moving through it, or the field would be experiencing a change in its strength. Theory In Faraday’s initial demonstration of electromagnetic induction, two wires were wrapped around opposite sides of a ring of iron. According to his assessment, of the electromagnetic properties, he knew that whenever the currents began to flow in the first wire, a wave would move in the ring leading to an electrical effect on the side that was opposite. ...
