THE INDUCTION COIL

Its Varieties and the Differential Indications for Their UseIn the centre of the coil and surrounded by the soft iron wires is placed a soft iron rod. One end of the rod is bent at right angles, so that the hammer on the spring is directly over and can move toward this soft iron rod, marked C. When the vibrating spring is resting against the platina-pointed screw D and the battery is connected with the coil, the current, as it passes over the wire of this primary coil, renders magnetic both the centre bun dle of soft iron wires and the soft iron rod.The magnetism is of sufficient force to attract the soft iron hammer on the spring, and draw it down or near to the magnetized rod C.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
