Magnet Size Problem

Hello. 🙂

I bought it from the magnet in the picture. I have 16. I bought it because I couldn't find a thin neodymium magnet.

Then I found a 20x6x3mm magnet, but I haven't bought it yet.
What kind of circuit should I rig for these magnets?
I don't think this circuit is compatible with my magnets.
