Description
The nineteenth century saw a remarkable expansion of knowledge of electricity, including study of the magnetism associated with wires carrying electrical currents. One who wrote on the subject was the German teacher Hermann Grassmann (1809-1877). This is a representation of a current element after the ideas of Grassmann. The model is part of a collection of surfaces prepared by Richard P. Baker, a mathematician at the University of Iowa.
This particular example of the model was on loan from Baker for exhibition at MIT from 1939 until the mid-1950s. It, along with the other models in accession 211257, came to the Smithsonian from MIT in 1956.
