Lenz's law demonstration

  1. Aug 3, 2011 #1
    Dropping a strong magnet in an aluminum tube is cool, but what will happen if magnets are dropped at the same time in tubes of aluminum and glass that are adjacent? Or at a defined distance due to strength of the magnets? Somebody probably has thought of this and demonstrated the results. It seems to me that the motion would be quicker but still slowed to normal gravitational pull, a hitchkicker of sorts.

    The magnet dropped in the aluminum pipe will eventually reach a terminal velocity as it creates currents in the pipe that create a B field. The one in the glass will just accelerate at g since its an insulator.
