On the Magnetism of Eledrodynainic George Gore, * I HAVE made some experiments ou the influence of hightemperatures upon the magnetic condition of electrody-namic spirals formed of iron, copper, and platinum, the heatbeing obtained by means of a voltaic battery. Experiment 1.—Two horizontal spirals of wire, A and B, fig. 1,ri-. were employed. A was composed of a platinum wire 34(& cen-tims. long and 1*42 millim. thick, and B of a copper wire 349centims. long and 2*59 millims. thick—each being coiled into acylindrical helix about 3*8 centims. long and 16 centim. in dia-meter, with exactly the same number of turns in each ; theywere united by means of binding-screws, C. A magnetizedsteel needle, D, about 8 centims. long, was suspended in the di-rection of north and south (by means of a fibre about 35 or 40centims. long), with its south pole between and equidistant fromthe ends of the tsvo coils, which were about 3 centims. asunder;the needle was weighted at its centre by a little piece of of the wires was coiled in the direction of a right-handed,and the other of a left-handed screw, so that on passing the cur-rent through them the magnetism excited in their ends nearestto the needle was of the same kind; and the di
