Electromagnetnic Microphone

This is a journey.. into sound… Electromagnetic sound!

These mics are sold as ‘telephone pick-up coil’ for about £5 in Maplin. It’s a small pick-up coil in black plastic moulding with rubber suction pad to attach to a telephone, designed to pick up conversations for recording. Kind of like old-school spy equipment..

Anything electronic or electrical will generate a magnetic field, and this baby will pick up that signal..


..and it goes a little something like this:

  1. Library card reader
  2. Lift
  3. G4 Mac
  4. iMac
  5. Mobile phone
  6. Photocopier
  7. PC Laptop
  8. TV
  9. Payphone
