Coating Hypothesis - levitation
As a hypothesis, this should actually work quite well, I lack the materials to perform the experiment.
It involves the typical electroplating process, so that's all fine and dandy with no real changes there, except how you'd submerge the magnet in the solution.
Since we're dealing with magnets, it should be possible to keep the magnet levitated within the solution while it gets plated. The hypothetical process behind this involves a conductive disk of material, most likely aluminium or copper spinning underneath the solution, such as the disk being attached at it's center on a drill.
To test this to see if it's potentially viable, you should be able to cut a soda or beer can in half and attach that to a drill and put the magnet in a baggie, turn on the drill and see if the magnet hovers over the can and test to make sure it's not air movement using a coin of similar mass. If that works to keep the magnet levitated over the "Disk" (in this quick experiment, the beer can), then the disk should also viably work I'd think as well.
Anyone with the materials required for this experiment care to try it and post the results please?
