    Calculate the circumference of the pipe you are winding it around, then multiply that by 400.

    depends on many factors including, but not limited to ....
    strength of magnet, speed of rotation of magnet or coil ... depending on your construction
    you are going to have to build a prototype and experiment with measuring the results of different setups

    The link you provided is post #1 showed it lighting a LED. That is a first guess of how much it can make.

    By the way, we measure power in watts, not volts.

    By the way, the link said 500 turns, not 400,

    Good luck, it sounds like a fun experiment.
