Testing my Precious : Help

Greetings,

It's now a few days I didn't post, mainly because I am in trouble.
I wanted to test my coins and ingots, and I don't get the results I wanted.

I can ping them, and the sound "seems" to be correct, even if I still need to test it with my new phone and the app which reveals the coin when you ping it near the phone.

But when I use my magnets, to be honest, no matter the angle I use, anything that is not ferromagnetic just falls at the very same speed. And when I try to make the coins dance with the move of the magnet, they just don't interact.
I really would like to make it work.

You for sure saw the video I posted on the discord :

I use a pile of neodymium nothing happens at all, I fear they are not strong enough, but I don't know where to fetch better ones. And I do not trust TEMU.
Or would you advise me to seek an old hard-disk and fetch the magnets from it, like in the video? (I don't even know If I still have any).

Of course I can't buy the real electronic testers, way too expensive for me, and for what I buy (disproportional), but if you have any other methods than the glider, the dancing and the pinging, do not hesitate to reveal them :)
Especially for the very tiny silver coins.

Thank you
