The Physics of Dropping a Magnet Through a Copper Tube

[robhlee]

Hello,

say you have a cylindrical magnet magnetized through thickness (not radially) and you drop it through a copper tube. It will slow down. Is there an opposite force on the tube? If you were to hold the tube in your hand and drop the magnet inside, would the tube feel heavier?

Yes...
