Fig. 145.Solenoid. Fig. 146.—Polarity of the Helix.The whirls of one turn unite with those of the next. the turns constituting the field, or total number of lines offorce passing through the helix. This diagram shows the di-rection of current through the helix, the direction of the 164 PRA GTIOA L… … Fig. 147.—Testing the Polarity of ; Helix.The helix is connected to a floating cell. whirls around each convolution, and the resulting polarity.The action is similar for another set of convolutions woundover this set in the same direction, or for a solenoid composed of any number of layers…
