1777 – Oersted – bio

Hans Christian Oersted was born in 1777 in Denmark and was a physicist and chemist. He has been given historical credit for noticing that electric currents can induce magnetic fields, thus creating the concept of “electromagnetism”. While Romagnosi discovered the relationship between electricity and magnetism about twenty years earlier, he did not investigate it in depth. Oersted eventually determined that current in a wire creates a circular magnetic field around the wire. Oersted was the first to completely isolate aluminum.
