# Modelling The Sun’s Magnetic Field

• JvanDyne
In summary, the author is constructing a solar wind outflow model, incrementally relaxing a series of initial assumptions. He has now arrived at the stage where he wants to consider magnetism, and the MHD equations. He plans to approximate the sun's magnetic field as a north-south magnetic dipole. His question is, given his mathematical inexperience, are there any recommended books, etc. with regard to his interests, and secondly, more mathematically, how would he calculate the magnetic field at any point given a 2D solar model and obvious spherical polars?

I’m currently constructing a solar wind outflow model, incrementally relaxing a series of initial assumptions in a stage-by-stage process. I’ve now arrived at the stage where I want to consider magnetism – and the MHD equations. My plan is, in what seems the simplest starting point, to approximate the sun’s magnetic field as a north-south magnetic dipole. My question is, therefore, given I am (as a maths student) an EM newbie, are there any recommend books, etc, w/r/t/ my particular interests, and secondly, more mathematically, how would I, assuming a 2D solar model and obvious spherical polars, calculate the magnetic field at any point?

Thanks. And thanks again if you understood that.

EDIT: This - http://seismo.berkeley.edu/~rallen/eps122/lectures/L05.pdf (pages 3,4,5,6) - seems, for the earth, to exactly calculate what I'm talkling about, but I don't quite follow the absent steps(?).
