1. What is the relationship between angular speed, frequency, and period? 2. The generator equation is EMF = ωNBA sin(ωτ). In terms of this equation and your own observations, explain why the maximum induced EMF is + ωNBA. 3. Imagine that a not so benevolent dictator of a small nation has decided to increase his country’s electrical output by increasing the speed of the generators in its single electrical plant. Discuss the result in terms of the generator equation.

You are working for a company that produces generators for windmills. To test various designs, you have been tasked with building a laboratory that measures the voltage output from a generator. Before spending a lot of time, effort, and money you decide to set up a simple model of a generator for which you can calculate what to expect. Your model consists of Helmholtz coils to generate a well-defined magnetic field and a smaller coil of wire, in between the...
