How do you keep the metal object from sticking to the magnet when building a magnetic damping device? :rofl:

Not sure why the LOL smiley, but whatever. You use a non-magnetic metal for the damping rotor material. It's eddy currents that cause the damping force, so you want a non-magnetic metal with good conductivity. Aluminum works well, I think.

Ok thanks,

The LOL was on account of the powerfull damping caused by the metal getting stuck to the magnet irony.
