CHAPTER VII MAGNETIC CIRCUITS AND MAGNETIC PROPERTIES OF IRON 39. Magnetic Field due to a Solenoid.—A solenoid is a coil ofwire wound in the form of a… … T Turns Fig. 40.—Closed solenoid. The solenoid in Fig. 40 has T turns wound on a cardboard spool and isbent to form an annular ring. A current of i c.g.s. units flowing throughthese T turns produces a magnetic field of intensity 3C which field cantherefore be represented by 5C lines of force. If a…
