g. 1133. continuation of the motion for another 90° decreases the angle until it is again 0°, and theE. M. F. is again zero. The remainder of the revolution repeats this cycle ofchanges of the angle, but, as the conductor is moving inthe opposite direction relative to the lines of force, theE. M.… … 3044. The shape of the waves of this curve may befound by calculating the E. M. F. generated at successiveintervals of time; this E. M. F. will evidently be propor-tional to the sine of the angle which the direction of motionmakes with the lines of force (see Art. 3020), so that byconstructing at…
