haha! what if someone asks you how you proved the formula engraved on the sculpture? :D Ya, i did work out the terminal velocity time. This is because i made the assumption that the magnet almost instantaneously reaches terminal velocity when it enters the magnet. I proved this mathematically...

Vela, don't worry, i knew that it was the derivative. I wrote it properly in my paper. Scott, the equation they give is extremely complex and although i used that paper as a launching pad, i didnt know how to use the scaling functions, so i had to derive my own. if you are still interested...

Um, guys, i really need your help :)

okay guys, i think I am out of my depth on this problem. Im doing a long investigation on eddy currents, and i derived a formula. I am reaching the end of the investigation, and so i wanted to compare my experimental data to expected data. One of the factors i was investigating is the...

Oh, i get it! so just to double check F=mv/t and F=mg (in this case) mg = mv/t g=v/t t=v/g Is that right?

i know that the downward force on the magnet is mg i know that the upward force on the magnet due to the eddy currents is (B^2 times L^2 times v) divided by R where B is the tesla, L is the length of the eddy current, v is the velocity and R is the resistance. From here, how do i show that how...

Hey guy, Ive been recently investigating the phenomena of eddy currents, particularly that of a magnet falling down a copper tube. To the people who haven't seen it before, basically the magnet reaches terminal velocity in the copper tube extremely quickly, and takes a long time to leave the...
