Laws Of Iron's Magnetism

The laws showing the relation of the magnetizing forces of iron to the resultant magnetism have been flxed from experimente just completed by Prof. Reginald A. Fessenden of the Western university and A. E. Kennedy, until lately associated with Thomas A. Edison. According to the Pittsburg DUpatch these two electrlcians have been trying for a year past to solve thls law of iron's magnetism. The discovery wil], it. is claimed, greatly facilítate and cheapen the building of different eléctrica 1 equipnients, for by applying the formulae of the discovered law the many costly experimenta of iron in a plan will not be requlred. ïhis because the test of one pieco of metal wlll sufflce for a group. It is ostimated that manufacturera by applying thes formulae wlll save from 30 to 40 per cent in their work, and that the discovery will prove of great importance In othcr channela.
