Question

Now let's repeat the previous experiment with the four-loops coil. Starting from the far left of the screen, move the magnet to the right so it goes through the middle of the four-loops coil at a constant speed and out to the right of the coil. How does the average brightness of the light bulb depend on the number of loops of the pickup coil?

Answer 1

more loops around the pickup coil the more brightness that the light-bulb generates

Step-by-step explanation:

Based on the information provided within the question it can be said that the more loops around the pickup coil the more brightness that the light-bulb generates. This is because the pickup coil monitors the amount of power that gets transferred to create light, the more loops around the coil translates to more power which creates more brightness.
