Motional Emf Equation: gives the voltage induced on an object of length d moving through a field B at angle with velocity v . For angle information, see figure 1. Induced Emf of a Generator: shows the voltage produced by a generator as a function of the number of coils N, the magnetic field B , the area of the loop A , and the rotational velocity , given time t . Angular Velocity Equations: several other ways to write . f is frequency of rotation, v is tangential velocity, and r is radius. Usually, you'll be using 2 f .
