alleryWhich scientist demonstrated in 1831 that an electric current can be produced in a conductor with the help of a moving magnet?
AHans Christian Oersted
BHumphrey Davy
CJohn Fleming
DMichael Faraday
Answer & Solution
Correct answer: D. Michael Faraday
1. Producing current from a moving magnet is the discovery of electromagnetic induction.
2. The chapter states Michael Faraday showed this in 1831.
3. The option Oersted's discovery (1820) was the reverse: a current deflecting a magnetic needle.
