Note 36 — HISTORY OF TELEGRAPHS, (continued 3)
Reading edition
Mr. Bain means, by the deflected position of the coil, (when the current is passing,) its horizontal position, as shown in the figure. Its natural position, (when the current is broken,) is the elevation of the left hand end of the coil, in the direction of the arrow, carried up by the power of the spring, at the centre of the coil. This action of the spring is overcome, when the current is passing, to such a degree, as to bring the coil to the horizontal position as represented in the figure.
