Griitzner (12) subsequently investigated the physiological action of currents from a Stohrer's machine, in which two wire-coils with iron axes revolve in front of a powerful horse- shoe magnet. Each revolution yields four currents, correspond- ing as two pairs in respect of time-distribution. If 8 and N (Fig. 175) are the poles of the magnet, and I and // the coils.
