Faraday's law of electromagnetic induction states that the electromotive force (emf) induced in a closed circuit is directly proportional to the rate of change of magnetic flux through the circuit. Mathematically, it can be expressed as:

emf=−dΦdtemf=−dt

Where:

  • emfemf is the induced electromotive force (emf) in the circuit,
  • ΦΦ is the magnetic flux through the circuit,
  • tt is time.

In words, Faraday's law tells us that when there is a change in the magnetic field experienced by a circuit, an emf is induced in the circuit. This emf drives a current in the circuit, causing it to flow in such a way that it generates a magnetic field opposing the change in magnetic flux that produced it.
