- 1. Value of magnetic field calculation

2. the magnetic field is created by a current flow

3. to get the flux density at an arbitrary point in space near the current carrying conductor

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 the line is being injected by different RMS values of an AC current of 50 Hz. It is intended to have a mathematical model formulation of the resulting magnetic field, so that it is possible to know the Tesla value of the magnetic field directly when the RMS value of the injected current is known.

In other terms, the required solution shall be as follows: a mathematical function that has the current's intensity (in Amperes) and frequency (in Hertz), in addition to the cable's length and geometry (thickness, number of stranded wires, etc.) as inputs, then consequently outputs the magnetic flux density (in Tesla) at an arbitrary point in the space near (around) the current carrying conductor (i.e., stranded-wire).

Suppose that the stranded wire lies (coincides) on the x-axis in a Cartesian plane; this wire begins at (0;0;0) and stretches forward the positive x-axis until its length: what would be the flux density at a point P (x;y;z) located in the same plane, that has the following coordinates:

x = 1 meter

y = z = 0.15 meter

Thank you in advance
