When did Michael Faraday discover electromagnetic induction, the principle behind the electric transformer and generator?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 1831.
Michael Faraday discovered electromagnetic induction in the year 1831.
Faraday's experiments in 1831 demonstrated that a changing magnetic field can induce an electric current in a conductor. This fundamental principle laid the groundwork for the development of electric transformers and generators, revolutionizing the way electricity is produced and used worldwide. His discovery is considered one of the cornerstones of electromagnetism and modern electrical engineering.
