How to make and use electricity ... magnetism, which, though differing in many of their proper-ties, yet alike in many, and almost invariably accompanyingone another, and constantly merging one into the other, appearas if they were only different manifestations of one and thesame agent. BATTWJ. Suspend two copper wires (Fig. 2), each 12 inches long,and about 1-2 inch apart, with their lower extremities dippingabout 1-4 inch into mercury, so as to move with little resistanceeither toward or from each other. Place one wire of the bat-tery in the mercury, and attach the other to the hooks above

Figure 3 isthe same apparatus, with the connection so made that the cur-rent flows down one wire and up the other, and we have an 32 HOW TO MAKE AND example of parallel currents flowing in opposite the former case the wires mutually attract one another. Inthe latter there is mutual repulsion. Hence we obtain thelaw. Parallel currents in the same direction attract one an-other; parallel currents in opposite directions repel one an-other. An iuteresting illustration of the former part of this law canbe arranged
