A change in the magnetic flux passing through a loop of conductive wire will cause an electromotive force. The magnet passing through the copper tube could be inducing a flow of electrons making it temporarily a weak electromagnet. Although Copper in non-ferrous, it makes great electromagnets.
you have never said what the one tube is made of... is it aluminum?? So if it is.. then you have 2 tubes of non ferous metal.. Magnets should fall at the same rate or speed...

I've done this experiment myself, which is easy to explain. Copper is a conductor, electricity and magnetisim are intertwined. If you have moving electricity you always have a magnetic field, and with moving magnetic fields around a conductor then you have electricity. When the magnet is falling through the copper tube it icreates electricity, in turn more magnetisim, in little eddy currents.The induced mag.works against the natural mag to slow the fall.
I think it is because of eddy currents. when magnet moves through copper tube it induces currents which produce magnetic field opposing to the magnets. Both aluminium and copper are good electric conductors. steel is not as good as copper. This is my standard concept.
Everything has a magnetic force to a higher or lesser degree, but that key point is that everything is magnetic. That's how reality manifests in this realm.
I was going to be a smart ass and say that nuetrons do not have a mag field. However I checked & found out they are made up of charged quarks-which are balenced so-although in a sense they do have one - it is just balanced out to zero. Also if a nuetron is spun it can have a 'magnetic moment'....which means something, somehow, I guess. Prob. has something to do with black holes, & Relativity, or maybe...magic or something. I hate it when I cant be a smart ass! I'm gonna cry now.
The copper wire's diameter is less causing the magnet to come in contact with a greater area when it's inside slowing it down with just friction. Am I done here?
No, it's not friction... It's electromagnetics, what happening is the reverse of an electromagnet...
Instead of running current through the solenoid to produce a magnetic field, you are running a magnetic field (a magnet) through a solenoid to produce an electric current.
The energy is not being lost to friction, it's being converted into electrical potential energy.
You're not done here, go learn about electromagnetics and the right hand rule!
Hmm, I think it's just that the magnet induces a current in the copper, which produces a magnetic field. This is the force that acts back on the magnet, slowing it down.
doesn't work for aluminium? well in that case theory of induced currents collapses, because aluminium in nearly as good conductor as copper. but aluminium is also diamagnetic (opposes itself to external magnetic field)
Actually it does work in aluminum, just not quite as well, because (as you said it is not as good of a conductor). However I will disagree with it not being nearly as good. Its pretty close. Ive not tried the experiement with an aluminum tube myslelf so cannot comment on how much of a diff. there is, however Ive seen similiar experiements with induced currents in aluminum holding back motion (such as with a magnetic pendulum and a large piece of aluminum) and theyve seemed to work just fine.

Well friction plays a key part here.

Haha, we'll be able to alter gravity when we figure out exacly what gravity is.

Oh how much you can fuck with the minds of the masses with such little facts such as the lenz law...
MrAwsome514 1 year ago
lenz law states that the direction of the magnetic field produced is set to oppose the motion of the magnet.

And it doesn't work for the aluminum because aluminum isn't nearly as good a conductor as copper.
