The galvanometer, first invented in 1802, was a means of detecting electric current. It consisted of a needle that was deflected by the magnetic field that electric current created; ...

Figure 3. A “newer” galvanometer, circa 1880. Without going into the haggling involved with my procuring the galvanometer in Figure 1, let's just say the antique vendor wasn't knowledgeable about ...

In a mirror galvanometer, a coil twists a wire that is connected to a mirror. By shining a light on this mirror and having the reflected beam bounce around several other mirrors, ...

The tangent galvanometer still holds its own in the testing-room for simple tests; and the lineman's detector is still indispensable on the score of its portability.
