A milliampere meter is an instrument for measuring amperage and maybe of the terrestrial, or of the dead beat form. The first is in fact a compassneedle which is deflected from its proper position on account of the passageof a current of electrification through a wire placed near it. The amount ofdeflection is read upon an appropriately arranged scale. The second formconsists of a magnet suspended upon pivots between two other magnets, andthe indicator comes to its proper position on the scale without oscillation,and the position of the instrument is unimportant, hence it is the more de-sirable form to
