This is a physics demonstration that I designed to illustrate how a Drop Tower type ride, as seen in this video https://youtu.be/Fk4exX29Tzo , utilizes Lenz's Law to slow the descent of the "slider" holding the riders. The demo consists of two lengths of pipe: one made of CPVC and the other of copper, both 1/2 inch in diameter inside. A short section of 1/2 inch wooden dowel connects these two pipes together. A neodymium ring magnet (K and J Magnetics RX8C4) is held by a 3D printed slider, which I created to hold it securely. To conduct the demo, I hold the pipe assembly with the CPVC portion at the top, allowing for free fall, while the copper pipe remains at the bottom to provide magnetic braking.
