he axial current, and hence the force onthem is less than on the south poles which are close to thecentral conductor. Thus rotation takes place. The results we have just been considering as to the motionof a circuit carrying a conductor in a magnetic field haveimportant practical applications. The… … Fig. 210. Fig. 211.
