When fully saturated, annealed charcoal iron wire will carry 150,000 lines to the square inch, and iron disks 132,000. For a Gramme ring of iron… … the ring carries only half of the lines, as shown in Fig 1. Hence the total section of the iron is 2 S. The iron ought to be only half saturated when the machine is carrying its normal load, and hence the quantity must be again divided by 2. If, for example, the armature is to give 102 volts at 750…
