The intended mathematical model is similar to the one in the publication: DOI:10.1051/itmconf/20181901010 But instead of a ribbon busbar (as object geometry) : a stranded wire

Sorry berkeman, the wire thickness is of 70mm2 (7cm2), as bad as can be in math :p

Exactly: I would like to calculate the magnetic field, resulting from the passage of an AC current, in a stranded wire of 70cm, from a distance (with respect to the line) of 1cm. Thank you

Thank you for this amazing explanation, berkeman. What about when I am a centimeter away than the wire which has 70cm of thickness?

Thank you again berkeman, I did not fully understand the phrase: "is that the wire is thin with respect to the distance away that you are measuring the field". Would be greatly if you could kindly rephrase

Indeed, it does. each stranded wire results in its unique magnetic field. The eventual (total) magnetic field is the superposition for each of the sub-generated magnetic fields (due to each wire).

Thank you for your time and consideration dear berkeman, "Your" post #4 contains merely a concrete form of Biot-Savart law. If you carefully pay attention to the title "your" Fig. 12.3.1, "your" equation is ONLY valid for calculating the magnetic field emitted around a single straight wire. I...

No. The link that you have provided contains 0 equations. Accordingly I cannot say that I have obtained any mathematical-based information. Considering that I have a null mathematical background, I still can be sure that the link that you have provided hasn't got anything to do with maths

Thank you but I only need a mathematical model that actually calculates the B-field (I am not interested at this stage to derive a relation between the B-field exposure and human induced diseases)

No not really. When I know the B-field resulting at a point P (x;y;z) near a current carrying conductor (due to the passage of a current in that conductor) I can reciprocally know the initial amount of the current, causing hence the creation of that B-field. It is simply the "how" to calculate...

1. Can the Biot-Savart law calculate the resulting magnetic field due to an AC current, flowing in a stranded wire? 2. I want to make this calculation for the following reason: due to the proportionality between the current and its resulting magnetic field, If I know somehow the Tesla value of...

1. Can the Biot-Savart law be applied for alternating currents? 2. If it is a 3-phase system, assumed perfectly balanced, each of the wire carries the same amount of current. Accordingly, I am only concerned about knowing the Tesla value of the current that is passing in the current-carrying...

Thank you berkeman. 1. I have found in my research nothing more than the Biot-Savart law. 2. Consider that you have a three-phase electrical power transmission system and that it is intended to calculate the flux density at a point P as described resulting from the flow of current in the Phase...

Hello, Assuming that we have a single-phase electrical transmission line (short distance (< 50 km), stranded, non-isolated, made of aluminum conductor steel reinforced), I would like to know the resulting magnetic field (shape, structure, absolute value, and all other possible details) when...
