Página 252 - Before having any knowledge of the method given in the above account, I had succeeded in producing electrical effects in the following manner, which differs from that employed by Mr. Faraday, and which appears to me to develop some new and interesting facts. A piece of copper wire, about thirty feet long and covered with elastic varnish, was closely coiled around the middle of the soft iron armature of the galvanic magnet described in Vol.
Página 246 - But with the 1060 feet of copper wire (a little more than one-fifth of a mile) suspended several times across the large room of the Academy, and placed in the galvanic circuit, the same magnet sustained eight ounces: that is to say, the current from the galvanic trough produced greater magnetic effect after traversing this length of wire, than it did without it. " From this experiment it appears that the current from a galvanic trough is capable of producing greater magnetic effect on soft iron after...
