1. de la rive's floating battery
A small galvanic couple, immersed in a little floating cell and connected through a coil of wire immediately above them. When the exciting battery solution is placed in the cell the whole, as it floats in a larger vessel, turns until the coil lies at right angles to the magnetic needle. Sometimes the two plates are thrust through a cork and floated thus in a vessel of dilute sulphuric acid.
A magnet acts to attract or repel the coil in obedience to Ampére's Theory, (See Magnetism, Ampere's Theory of.)
