Nature of the electric force or forces ; Relation of the electric and magnetic forces ; Note on electrical excitation
A scientific paper by Michael Faraday, published by the Royal Society in London in 1838, setting out his theories on electricity and magnetism for fellow natural philosophers. The single picture is a plain line drawing of an apparatus, a large sphere joined to a rectangular box with a long rod and a thin stem, shown on a cream page. A designer might take its spare, schematic diagram style and clean geometric forms as a model for technical line art.
