CHAPTER III.
INDUCED MAGNETISM.

Fig. 11.

EXPERIMENT 24. To find whether we can magnetize a piece of iron without touching it with a magnet.

Apparatus. Horseshoe magnet, H M; iron filings, I F ([Fig. 11]).

52. Directions. (A) Hold the armature of the magnet in a vertical position ([Fig. 11]), its lower end being directly in a little pile of iron filings.

(B) Bring the N pole of H M near the upper end of A, but do not let them touch each other.

(C) Keeping A and the pole of H M the same distance apart, lift them. Do any filings cling to A?
