Ldestone in silver case with keeper, made by George Adams, Fleet Street, London,

This lodestone formed part of the mechanics apparatus made by George Adams for King George III. It consists of a piece of natural magnetite in a silver case, elegantly engraved with the royal coat of arms. The lodestone was balanced on one arm of a beam. Then a piece of iron or steel was brought into position beneath the lodestone. The resulting downward force was balanced by adding weights to the other arm, thus weighing the magnetic attraction.
