le itself.In principle the tangentgalvanometer resembles themagnetometer described onp. 7, the linear scale andbar magnet being replacedby the circular coil carryingthe current. The same precautions witli respect to reading both ends of the pointer, and reversing the deflection so that the reading… … Fig. 47. III. TANGENT GALVANOMETER 55 at the centre of the coil is sensibly uniform for only a small area, theneedle must be as small as possible; if too large it is not in a uniform^field, and the relation given above will not hold good. In making observations, the deflections should be neither…
