Which scientist published the law of induction in 1831?

• A. Michael Faraday
• B. Georg Ohm
• C. Alessandro Volta
• D. Thomas Edison

Answer: (A)

Electromagnetic induction is the generation of an electric current or voltage in a closed circuit caused by a changing magnetic field. Michael Faraday demonstrated in 1831 that moving a magnet relative to a coil or changing the magnetic flux through a circuit induces an electromotive force, establishing Faraday's law of electromagnetic induction. This fundamentals-underpin devices like generators and transformers, which convert mechanical energy to electrical energy or change voltage levels. While Ohm is known for V = IR, Volta for the first battery, and Edison for practical electrical systems, none published the induction law in 1831 like Faraday did.
