Anything that you hear can be attributed to this generated sound, unless you believe that your ears can transduce varying electroagnetic fields into sound. |

Lol na. It was being recorded to a high quality dictaphone and put through audacity. Now its time to remove the coil from inside the unit and keep the coil and magnet apart. lol ..just a passing experiment, you never know till you play with things. Then I might drop both into salt water too lol. |
