[NJARC] Bar Magnet wanted

[Angelo Napoli]

Hi Rob,

Lowes actually has several drawers of science fair stuff in with the screws, nuts and bolts section and may have magnets as well. Edmund Scientific is not cheap but also a good online source also.

  Hi All,
  I am doing a program on telephony at a school and would like to recreate the device at our museum with the microammeter and bar magnet, to help explain how a dynamic microphone works.  Does anyone have a bar magnet kicking around, or know a good source for stuff like that.  Will also need a zero-center microammeter.

  Thanks, 
  Rob
