The correct answer is electromagnetic induction.

Key Points

  •  Electromagnetic induction is a current produced because of voltage production (electromotive force) due to a changing magnetic field.
  • This process happens when a conductor is placed in a moving magnetic field (when using an AC power source) or when a conductor is constantly moving in a stationary magnetic field.
  • The factors which influence voltage production are the number of cells and varying magnetic fields.

Additional Information

  •  Electromagnetic Induction was discovered by Michael Faraday in 1831.
  • Some of the applications of electromagnetic induction are as follows: AC generators, Transformers, etc.
