You need a 50\/50 mix of positive and negative facing magnets (e.g. left half all facing up, right half all facing down — other arrangements might also work!). You can use taller (e.g. 12x3mm) magnets instead if you prefer, but once you get above 4mm in total they'll stick out.\u003c\/p\u003e\u003cp\u003e \u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHorseshoe magnet version\u003c\/strong\u003e\u003c\/p\u003e\u003cp\u003eA magnet will sit on top fairly stably on its own, pressed up against the divider that runs across the diameter.
