How to source Ipad case magnets

I like the Magic Keyboard, but I want a case, which protects my screen, can be folded flush with the Ipad and is a stand, for a viewing angle / working with the (Mac) Magic Keyboard and Magic Mouse and for a writing / drawing angle.

Since there are no such products on the market i decided to build my own.

After I saw the amount of magnets, used in the ipad, I dont really want to buy every single, sligthly different, magnet.

Are there any ways to source the magnets used in the (Ipad) Magic Keyboard?
