Title
Iron filing diagrams from Faraday's experiments on delineation of lines of magnetic force
Reference
UK0108 OPC/1/003
Date
November or December 1851
Scope and Content
12 individual iron filling diagrams stuck to a large sheet of paper, many of which have been initialled on the reverse by Michael Faraday. These diagrams were made by Faraday in November/December 1851.
[Note: Faraday's experiments which produced the diagrams are described, and similar filing diagrams are illustrated, in ‘Faraday’s diary, volume 6 (11 November 1851 to 5 November 1855)'. The preface to that volume says;
"Folio vol. VI of the manuscript contains a considerable number of the actual specimens prepared by Faraday in 1851 to illustrate the delineation of lines of magnetic force by iron filings. The filings were fixed on cartridge paper by means of gum water, sometimes mixed with a solution of the ‘red ferro prussiate of potasssa’ which was found to leave a blue impression of the pattern after the filings had been removed or worn off”].
