Description (Brief)
A curved copper wire with a brass bearing, pivots on a small spherical cup and rotates in a wooden trough of mercury. Mercury removed from this specimen. Electrodynamic action is set up by current flowing through brass fixtures on the base and through the copper rotator, thus interacting with a external magnetic field set up by a separate coil wound around the wooden trough. Paper tag: "E / 782".
