I understand your situation Istookey, no one here where I live has some real good clue how to solve this problem. I tried some ways through the biot savard law but had not much luck... And just having those formulas written does not help me really much how to get there... I'll try again now see...

Thanx, but I think I'll have some difficulties getting those books... I'm in the italian speaking part of switzerland, but I'll give a try to my school library. If there is some kind of electronic version on this specific topic, could someone link it plaese?

Hello everybody! I have some trouble determinating the magnetic field generated by a circular loop of current. I'd use it as an approximation for the poloidal field in a Tokamak (field generated by the current in the plasma). I tried using Biot-Savard's Law but I'm getting stuck... I hope to...

It's still a great advance, because I can set the initial conditions for z velocity (so z(t)') to be 0 forcing the constant to be zero. So I have the problem solved for this specifical case. But as you say it still needs work for the more general case... Hope you didn't take me thinking you...

:bugeye: you got it! Well thanks very much! just for curiosity are you a math student?

... you're right... i made some confusion added a derivation grade for acceleration and velocity XD ... so, here are the correct ones: \left\{ \begin{array}[l]{l} m x(t)'' = q z(t)' \frac{x(t)}{r(t)}\\ m y(t)'' = q z(t)' \frac{y(t)}{r(t)}\\ m z(t)'' = -\frac{q}{r(t)}(x(t)' x(t) + y(t)'...

Yeah it's complicated indeed... and you got that right with z'''(t) I actually know what it should look like when it's solved (graphically i mean) and there is some pretty serious symmetry in the system... I'll give a shot with the cilindrical coordinates, but there will be much work at it...

Strange... But if you copy and paste it, it works 100%

hi guys, I'm solving a pretty complex problem: calculating a trajectory of a charged particle in a custom magnetic field. I arrive to the point where this very nice equation system blocks my way :P http://ramses728.altervista.org/img/phys.jpg hope you can help me somehow
