Change of electrical resistance in a magnetic field : with experiments on the change of resistance of electrolytes . magnetization alters the re-sistance differently along different vectors, the circles are chang-ed to ellipses. Goldhammers results for nickel and cobalt are magnetization produced an increase of resistance in each,while longitudinal magnetization caused a decrease of decrease in cobalt was less than that in nickel. His obser-vations on iron confirm those of Lord Kelvin, He does not claimas great accuracy for these results as for those on cobalt andnickel. Since the effects of transverse and longitudinal mag-netization are of opposite sign, it should be possible to find aposition for which magnetization would produce no effect. Thiswas verified for nickel and cobalt by experiment. With nickelthis occured v/hen the lines of flow made an angle of approximately70° with the lines of field. With cobalt the neutral positionwas between cf> = 30°and dj) = 60°. As with bismuth, antimony, andtellurium,•the results were shown graphically as in Figure
