...strength of a helix is greatly increased by the iron core. MAGNETISM AND ELECTRICITY. Fig. 150. 343. The Form given to an electro-magnet depends on the use to which it is to be put. The Horseshoe or U-shaped (Fig. 150) is the most common. The advantage of this form becomes apparent when attention... | |
