Found these coils in a old phone, they were used to drive a ball bearing in the ringer circuit that included 2 small brass bells. Each coil is 10k ohms. I plan to grind magnets to fit the core of the coil. Hopefully each one will work with 2 or 3 strings.

 Neodymium magnets are the best for small coils, they’re definitely one of the strongest magnets for pickups? 2 in parallel would cut the impedance in half, then you would either need to plug into the Lo input on your amp or use a Preamp/Lo-Hi Z impedance matcher to get the right output?

10K on the ohm meter. Impedance in a live circuit would be higher. I guess I could try 2 in parallel.

Is the 10K Resistance, or Impedance?

WOW, I didn't think small coils like these could put out 10k ohms  :-)
