hey, thanks a lot! that does indeed sound like it. now, i have to admit i have no idea how to apply it. let me rephrase the problem slightly so that hopefully we can derive some formula that can be plugged in computer.... lets image only 3 bar magnets sitting on a table randomly spaced. they can not move, but can only rotate around its center, it is 2D situation. there is no friction of any kind, no gravity and the only forces are magnetic forces. here is a picture where "x" is the point of rotation and coordinate center of each magnet, we have "top" magnet, "middle" magnet and "bottom", like this: [s- x -N] topMag: a=90, x=7, y=25 [N- x -S] midMag: a=270, x=18, y=19 [s- x -N] botMag: a=90, x=12, y=4 - input are 3 initial angles and 3 pairs of (x,y) coordinates - output are the new angles after system stabilize 1.) any idea how to derive equations to fit this case? 2.) for every initial position is there only one solution, even in 3D and with more magnets? 3.) gravity and magneto-electric fields act instantaneously on distance, right? so, is there any way to find out how quick reaction will be - how strong is rotational acceleration each instant for each magnet and how does it depend on distance? 4.) imagine now these magnets float in 3D space freely, and lets consider the middle magnet. it has a "choice" to be repelled to the right or to rotate its south pole to the left. will it rotate or will it translate? in other words, how to split acceleration to translation and rotation, what will it depend on if there is no friction and magnets are point particles with magnetic dipole moment? cheers

yes. ok, let me be really specific now since my message may appear confusing to others. 1.) i want to know if there is any software (QM or whatever) that can 3D simulate in real-time two neutral hydrogen atoms approach each other and form covalent bond. i want to see simulation of it, interaction based on some equations, as opposed to animation. basically, i want to see how "orbital clouds" change from one shape to another as covalent bond is formed. 2.) i want to try and do the same with classical mechanics, by simulating 4 particles - 2 electrons and 2 protons. when i start this simulation i want to see 2 neutral hydrogen atoms form like in that YouTube video. then, i want to see them approach each other and then form "covalent bond". now, before being told that it is impossible to use classical physics for electron atomic orbit, let me share this theory of mine. better yet, let me do this dude talk since he seem to have thought about it much more than myself: i simply can not believe that this was not considered in mainstream physics?! ...or was it? in chemistry and nuclear physics no one seems to take magnetic fields into account in regards to covalent bonding? everyone only talks about charges aka. electric fields, and on top of that classical mechanics actually predicts two spinning electrons will attract each other, given that enough magnetic moment is created to overcome electric repulsion. so, to answer my question about covalent bonds - the force behind covalent bond is MAGNETIC FIELD FORCE, which i hope to prove by simulating it as described above, only 4 charged particle but taking into account BOTH, electric as well as MAGNETIC fields. anyhow, i have done everything but SPIN, which you can see on those videos. there is still no bonding taking place which tells me this "spin factor" is very important indeed... all that lead us to the heart of my current problem: - imagine hundreds of bar magnets fall randomly on a floor. eventually they will orient in such way as to make complete system take on the "lowest energy" state. eg. if you put only two bar magnets next to each other they will rotate so that north pole of one is next to the south pole of another. how to go about simulating this?

it is interesting i could not find many particle-particle simulators that simulate electrical fields even thought dynamics is pretty similar to that of planetary orbitals. there are few i could find but they are mostly 2D and defining problem in mathematical/geometrical terms, with sin/cos or some harmonic oscillator functions. none, however, i could find that simulate CLASSICAL ELECTRODYNAMICS (Stochastic El.Dynm. - SED) in 3D n-body system and even less to include MAGNETIC FIELDS, which are the effect of moving electric fields, says Lorentz and friends... this is kind of situation and type of particles i want to simulate: http://en.wikipedia.org/wiki/Magnetic_field You may have mused in the past, why one of my ....., or my girlfriend's .... is smaller than the other? well, look at that photo above, CHIRALITY is built-in. this universe is rather quier, it pulls on one side more than on the other. breaking of the symmetry... - CHARGES & MAGNETO-ELECTRIC FIELD FORCES - Magnetic Fields - test1 Electric and Magnetic Fields: Positron & Electron do the helix dance DIPOLE MAGNETIC FIELDS due to moving electric charges (not spin yet)...
