[gour. Frank. Inst., New Eleetro-Magnet.--C%tmbrier increases the power of electro-magnets by augmenting the-extent of active surface at the extremity • ,,f the core and o~' the oscillating armature. He indicates various ways of doing this, which are all nearly equivalent in effect; he ~mllows the core and gives to the armature a prqject.ion fitting into the .cavity, or he attaches the projection to'the core, making it. fit a cavity • ~f the armature. A battery of eight or ten elements is as efficient, with his arrangement, am fifteen elements with an ordinary electromagnet. The residuary magnetism is not increased; it appears rather ao be weakened.--(Jompte, l~e~.d~,~.
