TitleUnpublished paper, 'On certain irregularities in the magnetic needle produced by partial warmth, and the relations which appear to subsist between terrestrial magnetism and the geological structure, and thermo-electrical currents of the earth' by Robert Were Fox
Date[1832]
DescriptionFox describes experiments on the impact of partial heat on the magnetic needle, discovering that there are no irregularities when the needle is completely surrounded by heat (i.e. water of a uniform temperature), but that when partial heat is applied, there are irregularities. He also describes theories about thermoelectrical currents beneath the earth's surface and experiments on the thermoelectricity of rocks, discussing the efficacy of different rocks as conductors and whether or not they have a positive or negative charge.
