Description: | E.251 (old departmental catalogue number in white cellire). LCE.52 (old departmental ctalogue number in aluminium paint, removed). MANU Unsigned. 19th century DES after DELEZENNE,Charles,Eduard,Joseph. 1844 Lille, France. This earth inductor or Delezenne circle used, in series with a ballistic galvanometer of the suspended magnet type, to calculate the vertical component of the earth's magnetic field. Conversely, if this value was accurately known, it could be used to calibrate the galvanometer. To measure the horizontal component a similar set up would have been used but the coil would have rotated about a vertical axis. | License: | http://www.hmag.gla.ac.uk/spirit/rights/ | Publisher: | Hunterian Museum and Art Gallery, University of Glasgow | Rights holder: | Hunterian Museum and Art Gallery, University of Glasgow | Subjects: | SCIENTIFIC COLLECTION : | Source: | Hunterian Museum | Creator: | Hunterian Museum and Art Gallery, University of Glasgow | Identifier: | http://www.huntsearch.gla.ac.uk/cgi-bin/... | Language: | en-GB | Go to resource |
