I almost feel bad for "spamming" you with all my videos, but it's such fun playing around with this feature that I just had to show you this new video (very short, around 800 KBytes).
The big sphere on top is magnetic, so all those small spheres below get attracted to it and since the magnetic force is much bigger than gravity the small spheres add so much force when hitting the big magnetic sphere that it get's blown away like a catapult. I guess the initial part (not the last one with the small spheres orbiting the big one) somehow ressembles fluid dynamics, like when water is pushed out of a small hole with high pressure. But it looks really interesting so I had to post this.
But on a sidenote I also have to say that this pushes newton to it's limits and only is that smooth because I used the faster (and much less stable) solver models.
