State Faraday's Law of Induction and explain what it means
What will be an ideal response?
Faraday's Law states that voltage induced across a coil is proportional to the rate at which the magnetic field strength through the coil changes. It is also proportional to the number of turns on the coil. This change can be brought about by rotating the coil, changing its shape, or changing the magnetic field strength. Because of Faraday's Law, current need not be restricted to batteries, but can be induced in a wire by any of the changes stated. Faraday's Law underlies generators.
