Ruhmkorff apparatus for the study of diamagnetism, 1882

An engraving from the 1882 popular-science work "El mundo fisico" showing a Ruhmkorff apparatus built specifically for studying diamagnetism. It is the classroom descendant of Faraday's bench setup: a bar suspended between the poles of a large electromagnet. One of very few period illustrations that names diamagnetism outright.
