Magnetism Trick Looks Like Anti-Gravity [Video]

In this video a neodymium magnet is dropped down a thick-walled copper pipe. The resulting effect is both hypnotic to watch and a demonstration of Lenz’s Law.

Jason Fitzpatrick is a warranty-voiding DIYer who spends his days cracking opening cases and wrestling with code so you don't have to. If it can be modded, optimized, repurposed, or torn apart for fun he's interested (and probably already at the workbench taking it apart). You can follow him on if you'd like.

    Pretty cool, looks like it uses the same principle as the magnetic brakes used in rollercoasters.

    @gilteon : Ultimately the Lorentz force.

    Neat effect.

    (I wish the player on the YT site stayed put and was also below the video like this one.)

    As a wee lad I got hold of some magnets. Golly Gee! MAGIC!
    A hungry mind read all it could find about the forces/principles involved.
    The kiddo inside says, “MAGIC, and the old man thinks he know better.

    I know what happens can be explained, but…maybe it IS magic.
