Answer:
Electromagnetic induction is the production of an electromotive force across a conductor when it is exposed to a varying magnetic field. Experiment: Two different coils of copper wire having large number of turns (say 50 and 100 turns respectively) are taken.
Electromagnetic or magnetic induction is the production of an electromotive force (i.e., voltage) 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 is a basic law of electromagnetism that predicts how a magnetic field will interact with an electric circuit to produce an electromotive force (EMF). ... EMF=−NΔΦΔt EMF = − N Δ Φ Δ t . This relationship is known as Faraday's law of induction. The units for EMF are volts, as is usual.
