See youtube.com/watch?v=dw73DcwIX-A for a similar example: you get more repulsion on average. | |
| Apr 7, 2014 at 15:55 | comment | added | user43487 | So is it in fact moving up and down but the movement is insignificant? I.e. Will the ring move into the magnetic field if the flux thru it is reduced? | |

| Apr 7, 2014 at 15:05 | comment | added | user43487 | So if an ac current is used does the ring rise and stay in a set position or move up and down as the magnitude of the current changes?? | |
