2. Electromagnetic induction - Wikipedia

   en.wikipedia.org/wiki/Electromagnetic_induction

   Electromagnetic or magnetic induction is the production of an electromotive force (emf) 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 .

3. Faraday's law of induction - Wikipedia

   en.wikipedia.org/wiki/Faraday's_law_of_induction

   Faraday's law of induction (or simply Faraday's law) is a law of electromagnetism predicting how a magnetic field will interact with an electric circuit to produce an electromotive force (emf). This phenomenon, known as electromagnetic induction , is the fundamental operating principle of transformers , inductors , and many types of electric ...

4. Faraday paradox - Wikipedia

   en.wikipedia.org/wiki/Faraday_paradox

   The Faraday paradox or Faraday's paradox is any experiment in which Michael Faraday's law of electromagnetic induction appears to predict an incorrect result. The paradoxes fall into two classes: Faraday's law appears to predict that there will be zero electromotive force (EMF) but there is a non-zero EMF.

5. FBI mnemonics - Wikipedia

   en.wikipedia.org/wiki/FBI_mnemonics

   The various FBI mnemonics (for electric motors) show the direction of the force on a conductor carrying a current in a magnetic field as predicted by Fleming's left hand rule for motors [1] and Faraday's law of induction. Other mnemonics exist that use a right hand rule for predicting resulting motion from a preexisting current and field.

6. Blondel's experiments - Wikipedia

   en.wikipedia.org/wiki/Blondel's_Experiments

   Basically experiments show how Faraday's basic law, that is the one that takes into account only flux variation, cannot be the general law of induction. In fact it is necessary to include also the contribution due to Lorentz force to obtain the general formula.

7. Lenz's law - Wikipedia

   en.wikipedia.org/wiki/Lenz's_law

   The current induced in a circuit due to a change in a magnetic field is directed to oppose the change in flux and to exert a mechanical force which opposes the motion. Lenz's law is contained in the rigorous treatment of Faraday's law of induction (the magnitude of EMF induced in a coil is proportional to the rate of change of the magnetic flux ...
