Len'z law and a interesting video!

  1. Please what this.
    This video will describe Len'z law from 0:00 till 1:25
    You can skip till 1:25 and see the interesting part to understand the following question.

    * Is the aluminum cylinder pushing the magnet down with a higher or lower or the same speed at the initial speed passing only the copper pipe?
    The guy says it pushes the magnet down so no details were given about the speed.
    Why does this very interesting phenomena happen?!
    And do you think when the magnet is approaching the aluminum cylinder its becoming slower and slower because a force is repelling in? Or nothing happens until the magnet passes the cylinder?!

  3. Ow yea and do you think current is still induced with the presence of that aluminum cylinder?
