Yes, you're correct about the flux resistance. I didn't experience any on the needles, perhaps they're not aluminium, they could be carbon fiber, but I didn't think they'de bother using that for knitting.

Something interesting to try, take a few cylinder magnets, place them opposites on the needle and flick one... The rest bounce around until they settle, they make good "shock" absorbers and the motion is very intriguing. If you pull down the second last one from any end and let it go, the rest will pass on the motion and the one at the end will fly off like a rocket. If it has nowhere to go it comes back and the magnets vibrate very fast. I tried using this by placing coils all the way down the shaft. It works a little but the opposite force impedes the vibration.

However, the needles are strong and straight.. I can only assume they are aluminium.

Where did you get cynlider magnets??

thats one of the few types i haven't gotten my hands on..

i actually tried to design a shock absorber like that years ago, but also had solenoid coils around the magnets for generation.

i ended up abandoning it because of an issue whith abrupt jolts,. both generation and absorbtion decays when the magnets are moving quickly.
would work great for slowly going over a speed bump,

but hit a crack in the road at 30mph would be a whole other issue
