Learn about electromagnetic induction , how it works, and its applications in generators and transformers. Electromagnetic Induction Class 12 Notes Chapter 6 1. Magnetic Flux The magnetic flux linked with any surface is equal to total number of magnetic lines of force passing normally through it. It is a scalar quantity. 2. The phenomenon of generation of current or emf by changing the magnetic flux is known as Electromagnetic Induction […] Electromagnetic induction is the process of generating an electromotive force (emf) or electric current in a closed circuit due to a changing magnetic field . This can be achieved by moving a conductor through a magnetic field or by varying the magnetic field near a stationary conductor. The induction of an electromotive force by the passage of a conductor through a magnetic field or by a change in magnetic flux in a magnetic field is known as electromagnetic induction. This happens when a conductor is placed in a moving magnetic field or when it moves in a fixed magnetic field.
