on in the coils at each half revolution, we have a con-tinuous current in the galvanometer, whose amount dependson the rapidity of rotation. We can by the mechanicalarrangement shown set the instrument so that the axis ofrotation is horizontal, vertical, or in any other position, in 3^4… … Fig. 211. If we compare Delezennes Circle with the coil of Fig. 187, c,placed in the magnetic field, we can see that the inducedcurrent is such as would cause the coil to rotate in the oppositedirection. The expression of this result may be modified byadopting Faradays conception of a finite number…
