The explanation of these effects is as follows : — The electro-magnet always retains a slight residual magnetism, and is therefore in the condition of a weak permanent magnet ; the motion of the armature occasions feeble currents in alternate directions in the coils thereof, which, after being reduced to the same direction, pass into the coil of the electro-magnet in such...
