Q. Who discovered the link between electricity and magnetism?
Answer: Maxwell
Notes: The connection between electricity and magnetism was discovered by famous Danish chemist and physicist, Hans Christian Oersted in 1819. Starting about a decade after Oersted’s discovery, Michael Faraday demonstrated essentially the opposite of what Oersted had found–that a changing magnetic field induces an electric current. He achieved an electrical current from a changing magnetic field, a phenomenon known as electromagnetic induction. Following Faraday’s work, James Clerk Maxwell developed equations, formally unifying electricity and magnetism. So it was Maxwell who formulated the relationship between electricity and magnetism.
