Scientist of the Week
I was born on September 22, 1791.
I was an English scientist who contributed to the study of electromagnetism and electrochemistry.
My main discoveries include the principles underlying electromagnetic induction, diamagnetism and electrolysis.
It was by my research on the magnetic field around a conductor carrying a direct current that I established the basis for the concept of the electromagnetic field in physics.
I also established that magnetism could affect rays of light and that there was an underlying relationship between the two phenomena.
