a. Use Faraday’s Law to derive the expression for the induced EMF for an ordinary slide generator, being careful to explain the steps, like on an exam.
b. Use that to estimate the EMF generated across the wingspan of an airplane flying toward Minnesota. Use the same 55.66 μT pointed 70 degrees downward.
The wing span is 35.78 meters and cruising speed is 907 km/h.
c. First conceptual question. There is obviously not a circuit or a current for a real airplane. Does that mean there actually is no EMF, or if you are sure there is an EMF, explain (with a careful diagram) the non-Faraday reason that causes it.
d. Second conceptual question. Even though the voltage is much smaller than (about 1/10th) what a real electronic device would use, assume you want to use this voltage anyway. You propose a strategy to connect a copper wire from each wingtip to your
device and get current and energy to flow, and realize it won’t work because it is like the example in class with a square loop in a uniform field. Explain.
