| Oct 26, 2022 at 16:12 | comment | added | joojaa | @OliverWalters it heavily depends on the particular arrangement of coil to magnet Sure the way you have drawn it seems to do so. But the magnetic field isn't entirely constant and once in motion you have bigger grip area... But yeah | |

| Oct 26, 2022 at 14:29 | comment | added | Oliver Walters | @ElliotAlderson It seems obvious to me that two opposing magnets are just going to cancel each other out in a voice coil - but my colleague, a test engineer working on this, is claiming that is working better, creating higher amplitude oscillation. I want to say that's impossible, and that there's something wrong with his experimental setup, but I'm not an expert on magnetism, and am wondering if there is a way this could happen? | |
