The sparks vary with the power of the instrument. An induction coil has been made that gives a spark over 40 inches in length a result incomparably greater than that obtainable from any electric machine. The induction coil may be used to produce any of the effects of Motional electricity, it being at the same time nearly free from the limitations which atmospheric moisture places upon all electric machines. Note. For an ordinary Ruhmkorff' s coil, one to three Bunsen or potassium bi chromate el...ements will suffice. The effect of the coil is generally increased by placing, in the base of the instrument, a condenser made of many sheets of tinfoil separated by layers of oiled silk. Alternate layers of the tinfoil are connected, t. E. , the first, third, fifth, seventh, etc. , layers are connected, as also are the second, fourth, sixth, eighth, etc. The odd numbered layers are connected with one end of the primary coil ; the even numbered layers with the other end. One object of this is to prevent the spark otherwise produced at the break-piece of the primary circuit.
