How do you appreciate the Faraday’s law, which is the consequence of conservation of energy?

Answer»
  • Law of conservation of energy says energy neither be created nor be destroyed, but can be converted from one form to another. 
  • Faraday’s law says whenever there is a continuous change of magnetic flux linked with a closed coil, a current is generated in the coil. This induced EMF is equal to the rate of change of magnetic flux passing through it. 
  • We have to do some work to move the magnet through a coil. This work produces energy. 
  • This energy is converted into electrical energy in the coil. 
  • In this way conservation of energy takes place in electromagnetic induction.
