In what year did Faraday report electromagnetic induction?

• A. 1789
• B. 1831
• C. 1893
• D. 1905

Answer: (B)

Electromagnetic induction is demonstrated when a changing magnetic field produces an electric current. Faraday showed this in 1831, with experiments where moving a magnet through a coil or altering the magnetic flux through a circuit induced current. He published these findings that same year, marking the first clear report of electromagnetic induction. So, 1831 is the correct year because it’s when Faraday conducted and documented the discovery. The other years don’t fit the historical record, as they fall outside the time of his experiments and publication.
