Unable to account for frequency related to Magnet being pulsed by Inductor

@Bep

I tried 90 turns of #30 magwire around a chem-wik  spool which fit snuggly over the neo. I only got about 3Vpp output and was only able to see the pulses/ringing. I did not see the 4900Hz signal when tuned to 35.714KHz nor could I see the two interacting signals at 959Hz, again just pulses/ringing.

Were you able to see the 4900Hz  on your setup?

Also, above you said that 959.4 is one of many that can be interesting.

Would you care to elaborate??

Edit: I will try a creamic mag and see if that makes any difference.

Hi , you could try to put something soft under the magnet to stop the vibration , to make sure it is not the coil magnet action , pretty much all coil sing at some freq , when they are not waxed .

hi to all
@duff
  i have read this  but  is no NEED TO PUT CAGE  OF ALUMINIUM OR COPER   TO PROVET  OF  SOME OUT  ENERGY  FOR THIS

BEACOUSE   YOUR FREK . FROM  COIL  IS TO LOW   <959 HZ>
AND CAGE IS NO ABLE TO STOP   OUT SAID EFEKCT OF YOUR COIL   
IF YOU HAVE SOME BIGER  FREK  OF YOUR COIL THEN CAGE  WHILL BE  NEED LIKE
150KHZ  OR MORE
WHIT THIS   YOU  WHIL NO PROVING IS THERE  NO EFFECKT FROM OUT SAID 
I LIKE TO SAY AND  YOU MAY TRAED  TO GET IN SOME  PLACE WHERE IS NOT ENY KID  OF CABLE  OF POWER SOURCE   
LIKE IN MOUNTING  AND THERE  TRAED THIS

BUT  FOR MY PROVING  YUO  WHIT YOUR MAGNET ONLY INCREASING  INTERACKTING FILD  FROM SOME  POWER LINE   AND  YOU HAVE  RESONANCE  FROM  THAT  POWER LINE  OF SOME  CABLE 

THE  S.M TPU HAVE VERY FAST SPINING ONE DIRECTION SMALL ELKTROMAGNET FILD
THAT IS  THE  ANSFER

On my OpenTPU attempt I have two areas where each has two rectangular magnets, one above the other. Even though all four magnets are the same, one side sings around 4880 and the other ~3000. I was trying to match an FFT. of video audio.

There was an 1800 spread between the two signals. That spread was segmented by 5 - 200Hz peaks. Those 200 peaks seemed to be the result, not the injection.

Well, the relationship of the signals is not correct so now I have a noise maker.

Metal coated mags suffer heat problems more easily when the right freeks are found.

The singing frequency seems to be a function of the magnet strength, coil specs and coil excitation. All of these frequencies I've found are multiples of Marco's dancing mag freek. The problem is very few of these multiples work. 959.4 is one.

I agree with you about the faraday cage. I need to rule out the 60Hz power line so I am going to try to find an area, maybe an 1 or 2 hours out of the city, where I can rule out that interference.

@BEP

I tired wrapping on half of a ceramic magnet with magwire and though the signal was somewhat different I still could not observe the 4900Hz when tuned to 35.714KHz.
