Overhead Transmission Line

Of course we can

But is it necessary we write ? As I remember it is dealt in detail in - As far as I remember Engineering Electromagnetics or so by hayt- that was the book we went through in our college days may be Mcgraw Hills

If I am not wrong, most of the books dealing with the maxwells equations will deal with it, this may be one of the favourite topics in the maxwells equation in time-varying field.

ı JUST WONDER how can we calculate this vaules if we want to learn, maybe I have a house near a transmission line and do not have measurement devices and only have pencil:)

Thats easy. If you can throw your pencil over the transmission line you are to close!

(No math involved.)

Please review Biot-Savart Law. You have all the equations in: www.en.wikipedia.org

If it is 100KVA then at around 100 m you should have around 100nT field strength.

If you want to know it for health security issues then 100KVA required 100 m and 100nT is a good upper limit if you sleep there. If it is a work place then it is not a preferable one...

There are devices from gigahertz-solutions.com with reasonable prices...

Or use the pencil rule! :-)

Yes.
