Faraday discovers diamagnetism

In 1845, Michael Faraday, working in his laboratory at the Royal Institution, hung a piece of heavy glass between the poles of an electro-magnet and observed that the glass aligned itself across the lines of force of the magnet. He further experimented on many other substances, with similar results, a phenomena that he named diamagnetism. These investigations showed Faraday that magnetism was inherent within matter. This led to his lecture “Thoughts on Ray-vibrations”in April 1846, which he expanded in the following years into his field theory of electro-magnetism. This was the progenitor for mathematical descriptions formed by Thomson, and especially for the seminal work of James Clerk Maxwell.«
