12 What is electromagnetic induction? Write the Faraday's law for elestro magneticnduction

Answer»

Electromagnetic or magnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field. Please like the solution 👍 ✔️

Whenever a conductor is placed in a varying magnetic field an EMF gets induced across the conductor (called as induced emf), and if the conductor is a closed circuit then induced current flows through it.Magnetic field can be varied by various methods -1. By moving magnet2. By moving the coil3. By rotating the coil relative to magnetic field

Faraday's second law of electromagnetic induction states that, the magnitude of induced emf is equal to the rate of change of flux linkages with the coil. The flux linkages is the product of number of turns and the flux associated with the coil.
