A MONSTER MAGNET.
Omk of oar leading army engineers has brought before the engineer classes of late an experiment of so gtartling a nature in its inception as to promise wonderful results. It is a monster magnet made of two Rodman guoa, which are connected at the br«ech. Around the magnet thus formed is wound about twenty miles of submarine cabJe. The cable is some that has been used in the torpedo service. It id wound and fastened in ft substantial manner, making a permanent magnet. When electricity is applied some strange results take place. For instance a bar of railroad iron 30ft long, if placed in the open cannon's mouth, cannot be drawn out by aB many men as can grasp it. Another instance of the strength of this big magnet was illustrated recently with a 3501b cannon ball. The shot was placed in the mouth of the cannon on the negative side. On reversing tUe electrical current it fell from its position, but was attracted to the opposite cannon and clung to its side. The positive current was then reversed alternately with the negative, and the beavy cannon ball played between the two cannons lika a tack between the poles of a toy magnet. Before many days there will be a public exhibition of this remarkable magnet.—' Safety Valve. 1
