Hi all, I'm trying to generate enough current using a solenoid to intermittently power an LED. My plan is to buy some enameled copper wire and wind it around pipe. This will be my solenoid. Then, magnets will be pulled through the pipe on string or what-not and, by Faraday's Law of Induction, an EMF will be generated. I understand that this EMF will be sporadic. It will depend on the number of windings and the strength of the magnets that are pulled through. Do you think it could be enough to intermittently light an LED?
