The moment you have all been waiting for! We can finally see if your prototype is able to produce real power. This is where the real engineering starts...
If you can quickly spin the axle on your generator to turn the magnets, and if that causes the LED to light up, then congrats! Unfortunately, I know that this tutorial has not been perfect, so maybe your circuit does not work properly on the first attempt.
True engineers are formed through failure resolution, and there is only so much I can do to help in that category. Look back through this website, consult external resources, or shoot me an email until you achieve success. This has by no means been a simple project, but the deepest learning occurs when you understand the science enough to make it your own.
