Abstract

Two types of astatic galvanometer are in common use. In one, two needles with poles reversed are united to form a rigid system, in the other, a single suspended needle is employed, the directive force of the earth's magnetism being compensated by an immovable magnet suitably placed north or south of the needle. (Hauy's method.)
