[NJARC] Bar Magnet wanted

[JOE CRO]

Rob - Just a thought, though it's properties are different, I have a selection of ferrite cores I keep around the shack for various projects. Would they work for you?

  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
