Hi everybody. I have a question on a magnetic field of a coil with N spire . I know the magnetic fields on point P that it has a about distance form coil center and staies on the central axis of the coil. Is possibile to determinate the magnetic filed of the coil on point P that does not stay on central axis of the coil? For example the point P staies on axis that has a distance above o below from central axis of the coil.
Sorry if i do not write a perfect english...
Best regards

That is done in advanced textbooks.
The simplest is to expand the magnetic scalar potential in Legendre polynomials.
Another method leads to elliptic integrals.

"Classical Electromagnetism" by Franklin does this in Sec. 7.10.1 using Legendre polynomials.
