Who had first obs A. Faraday
Oersted was a Danish physicist and chemist who discovered that electric currents create magnetic fields, which was the first connection found between electricity and magnetism. He noticed it when a compass needle is deflected when an electric current from a battery was switched on and off, confirming a direct relationship between electricity and magnetism.
While Faraday gives the concept of induction, Volta invented the battery and Ampere found about the current.
