My end goal is to analytically or numerically calculate the magnetic field inside and around a square conductor that has connection points at the top and bottom with a voltage applied.
Are there any software packages (mathematica, or even just C) that can do this given ANY current density in the conductor? The problem is that the conducting square does not have uniform conductivity, and can, in theory, have gradients, dead spots, etc, thus creating some eddy currents or some asymmetry that I cannot calculate easily by hand, hence numerical simulation would be perfect.
An example would be : a square conductor with leads at top and bottom. Some voltage is applied. The square conductor is split in two where the left side is rho_1 resistivity and right side is rho_2.
This specific one I think I can numerically do IF the leads connected the entire top, then its just integrate contributions from a number of line segments and you're done. But if the geometry of conductance is not simple I get stuck.
tldr: Any good simulation/numerical calculation for B fields given a specific current density equation.
