Excerpt from The Magnetism of Iron and Steel Ships: An Explanation of the Various Ways in Which It Affects the Compass Make another series of observations, at like intervals, along another line equally distant from the magnet, but on a plane a little below the upper face, and continue to do so until arriving on a level with the lower face of the magnet. Repeat these observations on the opposite side. We shall thus obtain a series of values, with coordinates for plotting them, which will determine the location of the poles and their dividing line; for where the deflection of the compass is greatest, there will be the focus of mag netic action, and it is evident that the more closely the points of observation are taken, the more accurately we shall attain the object sought.
