gpermanent magnet, WS, by a strip ofphosphor-bronze, which serves also toconnect the coil with the external cir-cuit. The deflections produced by thecurrent are read by observing through a telescope the imageof a scale of equal parts in the mirror M. On breakingthe circuit, the coil is restored to… … Fig. 259. 420 GAL VAX03IE TE Y. 2°. Its oscillations may be rapidly damped by the currentsinduced in the coil (see Art. 414). 3°. It may be made very sensitive by increasing the wind-ings and the strength of the field magnets. By the use of a shunt or divided circuit (Art. 390) therange of currents…
