2. EMI is revolutionary discovery that changed the way we live. EMI is revolutionary discovery that changed the way we live. In 1820 Oersted accidentally discovered that electric currents in wires produce magnetic field around them. In 1820 Oersted accidentally discovered that electric currents in wires produce magnetic field around them. Does the presence of the magnetic field induce current in the wire? Does the presence of the magnetic field induce current in the wire? In 1831 Michael Faraday experimentally discovered the relationship between electricity and magnetic fields. In 1831 Michael Faraday experimentally discovered the relationship between electricity and magnetic fields. Based on this principle generation of AC current is made possible. Based on this principle generation of AC current is made possible. What is Electromagnetic Induction?

3. Faraday’s Law of Induction The Magnetic Flux that are penetrating through an area A is defined to be The Magnetic Flux that are penetrating through an area A is defined to be Faraday’s Law of Electromagnetic induction states that induced Emf in the loop is equal to the rate of change at which the magnetic flux is changing with time. Faraday’s Law of Electromagnetic induction states that induced Emf in the loop is equal to the rate of change at which the magnetic flux is changing with time.
