rent is nowexerted perpendicularly to the direction of the magnetic needle, and itmaybe shown that the strength of the current is proportional to the sineof the angle through which the coil M has been turned : this angle ismeasured on the circle H by means of a vernier on the piece C. Thelatter,… … Fig. 827 instrument (837). Since the magnetic force at the centre of the coil M isthe same whether the instrument is a tangent or is a sine galvanometer, ^ -^ , ■ being the mean radius of the roil. The formula, then, for a siner galvanometer is C (C.G.S. units) . sm fJ, or C (amperes) -2rr7/ ^ iT,u…
