Electric currents and potential patterns in are studied.Resistivity surveying is the common application, but much there are many areas of physics (e.g. superstrings, high technology thin films) where fields cannot propagate freely in the familiar 3 spatial dimensions.
(The experiment is currently located in MP239; last write-up revision: Jan. 2008.)
