Any field is constrained by the geometry of the space in which it exists. Measuring such fields allows one to determine a wide range of physical properties: everything from the depth of the local water table to setting limits on the size and existence of extra space-time dimensions.
This experiment studies electric currents and potential patterns in conductors with different dimensionality. Resistivity surveying is a common application, but there are many areas of physics (e.g. graphene and other thin films) where fields do not propagate freely in the familiar 3 spatial dimensions.
(The experiment is currently located in MP226; last write-up revision: July 2016)
