Excerpt from Science Abstracts, 1900, Vol. 3: Physics and Electrical Engineering The author concludes that annealing largely increases the sm. Of metals that wiredrawing, rolling, or hardening strongly reduces s.m.; that per meability follows very closely the variations of sm. By reversing the order of the experiments, he finds that s.m. Is exactly equal during demagnetimtion, for the same interval of time. To that obtained during magnetisation. The s.m. Reaches a maximum value alter annealing at a bright red heat, no matter whether the specimen be cooled slowly or rapidly.
