Production of the magnetic field from 3-phase currents

[QUOTE="Delta2, post: 6501973, member: 189563"] You have misinterpret Ampere's Law (eq5), the integral that appears there is not a "simple" integral but a line or path integral around a closed curve. So (eq6) simply doesn't hold (it would hold if that integral was a simple integral as i said). Check here for more info about line integrals. [URL]https://en.wikipedia.org/wiki/Line_integral[/URL] More specifically check the section about "Line integral of a Vector field" because H in eq5 is a vector field. Anyway if you want to find H at the center of the three coils, then you have to make some extra assumptions about the geometry of the coils (for example are they solenoids?), the information from the currents only is not enough.
