Thank you. That is a good demonstration. I am planning to use long copper tunes to show the slowing effect due to the opposing fields and was wondering if I could incorporate this set-up and get to the strength of the magnets through that.

I teach high school physics and I would like to get maximum mileage out of my Lenz's law experiment/demonstration. I am going to get the students to drop magnets down a long copper tube to calculate the magnetic force using distance, time etc and making a direct calculation using Fnet=...
