Point for anna for this round. because clark is wrong. Hans Christian Ørsted was a Danish physicist and chemist who discovered that electric currents create magnetic fields, which was the first connection found between electricity and magnetism.
No, it was Maxwell and Hertz. About 150 years ago, James Clerk Maxwell, developed a scientific theory to explain electromagnetic waves. and hertz was a German physicist who first conclusively proved the existence of the electromagnetic waves.
Andre invented the astatic needle, a critical component of the modern astatis galvanometer, and was the first to demonstrate that a magnetic field is generated when two parallel wires are charged with electricity. while Michael Faraday FRS was an English scientist who contributed to the study of electromagnetism and electrochemistry.
