    Fig. 52. Let two magnets of a cubical form, and with their cog¬ nate poles upwards, whose superficies are plain and polished, be so joined together that between the two A and B may be the thin iron plate C. Let iron filings be sprinkled upon a tablet placed upon them ; then will these become arranged into a series, represented by the figure; in which the polar place of the strongest magnet B is clearly indicated; but over the plate C are seen scarcely any filings, and beyond this place all is in disorder. This experiment differs from the preceding, in consequence of the interposition of the iron plate C which produces all these irregularities of attraction ; preventing both poles from conjoining themselves in the middle, and making one common pole for the forces : it causes how¬ ever the forces of each magnet to remain distinct. But inasmuch as the magnet B is stronger than A, it the more strongly emits its forces to the sides which face it; forces which penetrating the iron fence disturb the order of the filings produced by A. experiment lxx. Fig. 53.* Let both the same magnets be located near each other without any intervening obstacle; but so that the poles of alternate name look upward. Over a little tablet [asserculufri] placed upon them, let there be sprinkled iron filings; then will these, as in Fig. 53, exhibit both
