My kid loves things that spin and refrigerator magnets. So when I saw her play with the gear magnet toys at the museum I knew we had to have some.
It is simply a set of customizable gears that you can press a 608 bearing and magnet into. The magnet was selected because it is the perfect size to press into the bearing, though I do recommend using a dab of glue to keep it permanent because tolerances can make some looser than others.
The gears also have 4 optional locating pins that allow you to stack them to make a gear train! (FYI Doing this makes them hurt to step on!)

Also note that I lowered the pressure angle in the model from what I used to help reduce the gear separation forces. My gears range from 15 to 25 teeth but the magnets are strong enough that you could do more.
