The electro-therapeutic guide, or, A thousand questions asked and answered . Thus we see, by the accompanying sketch, where a bundle of iron wiresis immersed in a primary field. This bundle of iron wires, insulated fromthe coil of wire, is called a core. The wire so wound about the core iscalled the primary coiV. How is induction modified?. The induction is modified or varied by several factors:First—By the strength of the primary —By the size of the primary —By the number of turns in the primary —By the length and thickness of the core.

THE SECONDARY COIE What is a secondary coil? A secondary coil is one of fine insulated wire outside of the primarycoil. It is of great length, and the only current that it carries is the one THE KIvECTRO-THKRAPKUTIC GUIDE 47 created by induction from the magnetized core and primary coil. Its currentis an alternating one, inasmuch as the current induced by the make ofthe galvanic current is in an opposite direction from the one induced at thebreak of the same. ?> ir -fv r- u s - r\ ~t f-^ C;\\\^A:\[\x^ L__/ The accompanying sketch shows a core, primary coil, field and secon-dary coil.
