Abstract
A wedge shaped piece of copper, the Graneau-Hering submarine, is propelled in the direction of the wider end when placed in a trough of current carrying mercury. Mercury in a wedge shaped trough carrying current rises to a higher level at the wider end which can be used to establish an uphill flow of mercury, Hering?s pump. An explicit expression for the driving force in these two situations is derived from Ampere?s original force law for the force between current elements. Two simple experiments are proposed to test the theory quantitatively.
