Copper Pipe Magnet

We have weird gravity here in Rockford Illinois. The neodymium magnets are super powerful and even though they are not attracted to the copper, they still produce eddy currents that buffer the fall as seen in the video. Lenz's Law make a great experiment for kids to adult. Also, great at parties when conversation goes stale.

the item emits a magnetic field which when going through the tube pushes the loose electrons around (same way electricity is produced) my guess is that the speed is slowed down because of the massive amount of electrons it has to push. Basically like sinking through a giant hole full of jelly.
-
yeah its a normal copper pipe but its a very strong magnet, it will work with a normal magnet but the effect will be less pronounced
-
How did you do that, I think about that every day...
-
What's happening is that has the copper pipe is moving through a magnetic field and electric current is being induced on the pipe which creates a magnetic field of its own which provides a force to act on the magnet.

Copper isn’t magnetic on its own, but it can easily produce a magnetic field due to inductance, as is shown here.
-
What if you had some sort of tube loop that moved upwards at a rate so that the magnet inside stays at the same place elate to the world?
-
It's due to inductance, the magnet generates a current in the copper pipe which opposes the magnet so it goes down slowly.
-
is this a normal magnet and a normal copper pipe?does it works with a normal magnet?

TAKE MY MONEY!!
