Unpublished paper, 'On the law which connects the various magneto-electric phenomena lately discovered by Dr [Michael] Faraday' by William Ritchie Ritchie describes experiments designed to the prove the law of equal and opposite reaction in relation to electromagnetism, whereby a current of voltaic electricity can induce magnetism, and likewise magnets can induce voltaic currents.
