If magnet was not rotated when dropped through the tube, would it simply stick to one wall in case of slightest imbalance?
I can't clearly remember my psychics class, But I think I'd fall a bit faster, as the movement through the pipe is considerable as well.
Yup, it's pretty cool. This was one of the most impressive demo's my physics professor did in our freshman physics class. The point is that as the magnet is falling through the copper tube it creates an electric current which then creates a magnetic field in the opposite direction of the magnet's movement. In other words, this is the practical application of the Right Hand Rule [1]. Two fun facts about it: first, if…
It'd be completely impractical, of course, but a whole lot of fun.
Earlier quoted context omitted.
Not sure where to get one at that thickness or diameter, but a specialized plumbing supply company can get you most standard size and diameter of copper piping. That one is huge, though. In theory, this should work with smaller, but powerful magnets, and thinner tubes, correct?
I don't think you can make a permanent magnet any stronger as it is. There is a certain limit. I think the size matters in this case. I can only find thin pipes for plumbing online, but I would really like the think one.

Could this be used as a kind of elevator tech? I'd love to ride one of these down a gigantic copper tube. It'd be completely impractical, of course, but a whole lot of fun.
It would take a hell of a lot of magnets to strap to a person to allow them to jump down a copper pipe though.

Not impossibly strong mind you, if magnets can hold a hundred ton train car off the ground I am sure they could slow the fall of an elevator.
I'd not want to be inside that elevator with anything magnetic in my pocket, though.

And at the end of the ride, you want to take a selfie and email it to all your friends but you can't because your phone is fried.
Where can you buy something like that. A magnet is around 150$, but I have no idea where to get a copper tube of that thickness.
It also works with a small neodymium magnet which can be bought for less than $1 and a small copper plumbing tube which costs about the same.
