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? 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? the brightness increases when the number of loops increases. the brightness decreases when the number of loops increases. the brightness does not depend on the number of loops.
