On a Uniform-Electric-Current Sir William Thomson, , * /CONCEIVE a closed circuit, CTABC, according to theV^ following description :—One portion of it, T A, tangen-tial to a circular disk of conducting material and somewhat * Communicated by the Author, having been read atthe Meeting of theBritish Association, Dundee, September 186/..

Ifall of the wheel were cut away excepta portion, C T, from the axle to thepoint of contact at the circumference,the circuit would form a simple rect-angle, CTAB, except the bifurcation of the side B C. Let a fixedmagnet be placed so as to give lines of force perpendicular to thewheel, in the parts of it between C the centre and T the pointof the circumference touched by the fixed conductor; and letpower be applied to cause the wheel to rotate in the directiontowards A. According to Faradays well-known discovery, acurrent is induced in the circuit in such a direction that themutual electromagnetic action between it and the fixed magnetresists the m
