 ... standing on three claw legs. Mr. Armstrong says that on several occasions he succeeded in raising the table without contact. It rose to the fingers held over it at a height of several inches, like the keeper of a strong electro-magnet.[9] ...

... person seated some distance in front of the window in the next room. A needle (D) was hung on a pivot behind the cardboard, so that its point could move along the bright trough in either direction; and on the needle was put the armature (A) of an electro-magnet which, when a current passed, would be drawn instantly to the magnet (E), and so stop the needle exactly at the point which it had then reached. A clock motor (Cm) was arranged in such a way as to carry the needle back and forth regularly over the slit; and the electro-magnet was connected ...

... Professor Dana, in 1827, the rationale of the electro-magnet, which' latter was exhibited in action. I witnessed the effects of the conjunctive wires in the different forms described in his lectures, and exhibited to his audience. The electro-magnet was put in action by ...

... receive vibrations to the lowest limit of waves that we have ever been able to measure. The X-ray is high on the scale and even the cosmic ray is far above its lower limit of detection. We are hunting for an electro-magnet, the largest and strangest electro-magnet that has ever been constructed. Perhaps it would be more accurate to say that we are seeking for a generator of magnetic force. It does not generate the ordinary magnetism which attracts iron and steel, nor the special ...

... counterpoise, i. The fever, n n', is brought back to its position of rest by means of a small counterpoise at the extremity of the arm, n. When the lever, A, is depressed, the pendulum escapes and sets the clock running. This depression is effected by means of an electro-magnet, E, whose armature, which is connected with the rod, t, t, lifts the arm, i, of the lever, and depresses A. The wires of the two bobbins of the electro-magnet end in two clamps, 1 and 2. The second of these latter is insulated from the clock-case. Both communicate with ...
