Say I have an electromagnet, (that I know the dimentions, geometry, material characteristics, etc) that I am driving with a current that is oscilating at some frequecy how can I calculate the maximum strength of the magnetic field that it can create at that frequency?(adsbygoogle = window.adsbygoogle || []).push({});

and the equations need to be valid for extream ranges, all the way up to say 1.5Ghz

What would be even better though, would be some real instructions on how to use maxwells equations, I could figure what I need to know from them, but ive looked through about 12 electromagnetics books and none of them did a very descriptive job a explaining them. Or answering pratical questions like "where do you find the equations that define the magnatization or polarization properties of a material you want to work with?" and almost all of them follow the equations with the words "but if we are not dealing with very large field strengths or high frequencies these equations can then simplify to ..." and they give you all the nice information about how to use those simplified equations, and they leave you in the dark about how to do anything remotly practical with maxwells equations.

any help would be greatly appriciated
