High quality exercise bicycles use Lenz's Law to add resistance--rather than friction, which wears out the parts.

I'm curious to learn if there are any changes in the braking materials after a few years of use :)

+Marinus If it uses len'z law (or dynamic braking electrically speaking) then no. There are no wear on the parts what so ever. However the current induced in the metal would create heat. If you had enough magnets falling down this tube one after another, after a while the tube would become warm.

+Dan Coulson Hi Dan, thanks for your comment, however, I wasn't speaking about wear :) 'sciencetoymaker' was. I am more curious about changes on molecular level. I know that magnetic fields can have influence on the integrity of certain metals over time.

So does the magnet slows down only in a copper pipe or in any non-attracted pipe to the magnets?

In a conductor, especially the best conductors such as copper, elemental silver etc.

I was unaware of Lenses Law. Thank you for the demonstration and explanation. What I would have liked to see was you connecting an electrical measurement to the copper tube to determine the level of electrical impulse created following Lenses Law.

Imagine if we could create some kind of metallic structure of copper, that reverses the induced magnetic field, so that instead of opposing the direction of the magnet, it adds to it. I know it couldn't be done, but an interesting thought none the less.

In U.S. military magnetic compasses such as those manufactured by the Cammenga Company, the magnetic card is dampened using this principle. Many compasses use liquid dampening of the needle. The U.S. military did not want a liquid filled compass. The U.S. lensatic compass has a copper ring around the circumference of the compass housing. The magnetic needle induces a magnetic field in the copper ring and this serves to brake or dampen the compass needle. Induction dampening.

I'm doing this for my science fair. Can you generate electricity and use it to light a led light from the copper tube while the magnet falls down? Pls answer and I never had physics class so pls don't hate

A slight correction in your short definition of Lenz's Law: An induced magnetic field does not really oppose the field that induced it. What it actually opposes is the CHANGE in the original magnetic field. So if the original magnetic field is diminishing the induced magnetic field will supplement rather than oppose it, trying to stop it from diminishing.
