Unfortunately it doesn't translate to 3 dimensions. I've done a little app for iPad using the bullet physics engine. And for some reason it's not stable at all and I can't figure out why. I'm pretty sure I got the equations right. I've played with all the parameters but the magnets spin out...

Rectification, I managed to make the triangle. Reducing the size of the dipole and increasing the magnetic force did the trick. I suppose the model gets more accurate when the dipole gets really small.

Alright, I got a prototype working, it's pretty fun. I wish I didn't have to work tomorrow, I would port it to the iPad straight away :) https://www.youtube.com/watch?v=92mLz4GMUPE Here this structure is not terribly stable which makes sense as the hexagon with a ball in the middle is not a...

Thanks. Indeed, it's just a toy, I don't need to be accurate here. Hopefully it shouldn't be too hard. I'll try to make a prototype in c# using farseer physics engine. And if it turns out ok, I'll make an app for my shiny new iPad 3 :) I'll limit myself to 2 dimensions. I'm really curious to see...

I'd like to simulate the interaction between these magnetic balls on my computer. I suppose they are magnetic dipoles, how would I go about finding out the forces applying between 2 of them in a specific configuration ? Do I need to find the magnetic field and then apply the Lorentz force...
