C. What can you deduce about the induced emf's dependence on the amplitude and frequency? How does this agree (or disagree) with Faraday's Law? . Now, we will explore how electricity can be generated from mechanical motion. Open the Generator tab, and set the pickup coil end to voltmeter. Ber Magnet Pickup Coil Transformer Generator Bar Magnet- Pickup Call S N Lawn a. Set the bar magnet strength to 80% and the Loop Area to 30%. Click the Show Field button to see how the field changes . Open the spigot such that the magnet rotates at 40 rpm. What do you observe in the pickup coil? Why does this happen ? b. Increase the spigot flow, such that the rpm increases from 40 rpm to 100 rpm, in steps of 20 rpm. What do you observe in the pickup coil? How do your observations agree (or disagree) with Faraday's Law? c. Reset the scenario using the Reset All button . Set the bar magnet to 80%, and the Loop Ares to 20%. Open the spigot such that the magnet rotates at 60 rpm. Now, increase the Loop Area to 100%, in steps of 20%. What do you observe in the pickup coil? i. How do your observations agree (or disagree) with Faraday's Law
