eter in which the strength of the deflectingcurrent is measured by the torsion exerted onthe suspension system. A ball-shaped magnet, shown at the right ofFig. 278, is suspended by a thread and spiral Gal.] 251 [Gal. spring between two coils of high resistance,placed parallel to each other in the… … Fig. 2 J 8. Torsion Galvanometer. The angle of torsion is measured on the horizontalscale at the top of the instrument. In the torsion galvanometer, unlike the electro-dynamometer, the action between the coils and themovable magnet is as the current strength causingthe deflection. In the…
