A Modern Bréguet-Type Galvanometer
Recently the handsome little galvanometer (only 10 cm high) in Fig. 1 came into the Greenslade Collection. This is a design without a moving coil and, consequently, is very rugged. At the same time, John Daffron independently sent Tom Greenslade the picture of a similar galvanometer that he had made some years back and has been using for experimental work since then. These galvanometers are easy to build and can still be used in the lecture hall.
