Answer:
Faraday's first law of electromagnetic induction states that “Whenever a conductor is placed in a varying magnetic field, an electromotive force is induced. Likewise, if the conductor circuit is closed, a current is induced, which is called induced current.”

Answer:
Electromagnetic or magnetic induction is the production of an electromotive force across an electrical conductor in a changing magnetic field. 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.
Faraday's law of induction states that the EMF induced by a change in magnetic flux is EMF=−NΔΦΔt EMF = − N Δ Φ Δ t , when flux changes by Δ in a time Δt.
