| May 3 at 9:17 | comment | added | Markoul11 | "But what would happen if we used a very high ac Frequency, wouldn't that keep the wire centered?" That is a very interesting suggestion! Say for a example a 1KHz a.c. signal on the wire. Assuming the current to be of enough amplitude to compete with the field of the ring magnet theoretically this is possible I believe. The wire will continuously and very fast try to adjust keeping it at the center. But you have to experiment to make sure. | |

| May 3 at 9:10 | comment | added | Mo711 | Thanks for your answer, I am struggeling a little to understand the vectors superposition, which would result in a force pulling the rope to the inner wall. But what would happen if we used a very high ac Frequency, wouldn't that keep the wire centered? | |
