For this multiple generator you need 5 strong neodymium magnets, 5 insulated thin copper wire coils with 1000 turns and 5 LEDs. Place 5 modules with each coil attached to one LED on a wooden base. In the center is a vertical pivot. A CD with 5 strong magnets can spin on this pivot. The gap between the magnets and the coils is about 2-3mm. As you rotate the CD the moving magnetic field creates an EMF and all the LEDs light up brightly!
