Tesla Coil Plasma

  1. Jul 18, 2010 #1
    Okay, now I realize that this is from sci-fi, but I'm just wondering if it's possible to do this. In the movie, The Sorcerer's Apprentice, the guy uses Tesla coils to "make music." He said that when they fired, the did so at such a high frequency that it made sound. Is this possible?

    Yeah, it's dead easy. In fact using a solid state driver you inevitably get a musical note out of it because you 'chop' the drive at some frequency to avoid overheating the output stages.
    There's even a couple of companies that market what they call a 'plasma speaker' that uses the same principle. (It's a pretty lousy sound though)
