I am working on the project above ^ and I am having troubles. I am up to the point in the procedure were I have to test the generator by hand to make sure it works. Sadly it does not
. I have followed all the troubleshoots and I still am not able to get the LED to light up. Please help, I have to be done testing by May 8th.

samsamthebam - This experiment should be pretty straightforward. If you wound the coil carefully, scraped the insulation off the ends, the LED is functional and there is not a short circuit between the coil and the core, you should get the LED to flash. Because the poles reverse themselves each magnet passes close to the core ends, it is producing AC current. The LED is a diode and will only conduct when the voltage is positive on the anode. Therefore the flashing. In that you aren't getting any flashing do you have a meter to test the continuity of the coil winding (use the ohmmeter) and check connections to the LED. Make the insulated magnet wire is not shorted to the iron core of the coil. Are the magnet poles N & S arranged properly around the hex nut? Check these issues and you should be able to correct whatever is not set up right.
