A MONSTER MAGNET.
One of our leading army engineers has brought before the engineer classes of late an experiment of to startling a nature in its inception as to promise wonderful results. It is a monster magnet made of two Rodman guns, which are connected at the breech. Around the magnet thus formed is wound about twenty miles of submarine cable. The cable is some that has been used in the torpedo service. It is wound and fastened in a substantial manner, making a pop manent magnet. When electricity is applied some strange results take place. For instance, a bar of railroad iron 30ft long, if placed in tho open cannon’s mouth, cannot be drawn out by as many men as can grasp it. Another instance of the strength of this big magnet was illustrated recently with a 3501 b cannon ball. The shot was placed in the mouth of the cannon on the negative side. On reversing the electrical current it LTi liount;position, hut was attracted to the opposite cannon and clung to its side. The positive current was then reversed alternately wi„th the negative, and the heavy cannon bail played between the two cannons like a tack between the poles of a toy magnet. Before many days there will be a public exhibition of this remarkable attractive magnet.— Safety Valve.
