Electromagnetic induction is the phenomenon of producing induced current in a coil by changing the magnetic field. d. the process of rotating a coil of an electric motor. Answer: Electromagnetic induction is a phenomenon in which a changing magnetic field across a loop of wire results in the generation of an induced emf. Faraday's name is commonly associated with the phenomenon (Faraday induction), although in this century Henry's contribution has been recognized by assigning his name to the unit for inductance. The phenomenon in which electric current is generated by varying magnetic fields is appropriately called electromagnetic induction. Q.

When there is relative motion between a magnet and the coil, magnetic flux changes and hence an electromotive force is generated in the coil. Mutual Induction. Michael Faraday is generally credited with the discovery of induction in 1831, and James Clerk Maxwell mathematically described it as Faraday's law of induction. producing induced current in a coil due to relative motion between a magnet and the coil. Explain how Faraday's law describes the phenomenon of electromagnetic induction. Magnetic Flux: Electromagnetic induction is a phenomenon by which electromotive force is produced across a conductor placed in a varying magnetic field. Electromagnetic induction the phenomenon called electromagnetic induction was first noticed and investigated by michael faraday in 1831. In 1831, Michael Faraday carried out numerous experiments in his attempt to prove that electricity could be generated from magnetism.
