Unequal Volumes 2
If the bar magnet is enlarged at one end (see last diagram) it becomes a cone. The division into the two opposed conditions will still be equal, as in this an the next figure, but the volume will be so large in one as compared with the other that the nail which the positive end will still pick up cannot be lifted by the negative end unless the nail is ground to a fine powder. The negative end will then lift the same weight in total but only by dividing the nail over the whole volume.
Before this principle is applied to matter and space, it is necessary to correct the general impression that the earth is a magnet. By referring to the bar magnet pictured in the last figure it can be seen that its poles alone express gravity. The earth, on the contrary, expresses gravity at its center.
