Thanks for answering my question! Yes, the 'real' is not appropriate word. 'Total' would be appropriate. Sorry for that... However, what i really want to know is tha, Ampere's law gives us just some magnetic field that is generated by current 'inside' the ampere circuital. That means the...

I think the real magenetic field is sum of the magnetic fields calculated in each cross section of solenoid with various angle and same center axis when i apply Ampere's law. (Imagine the cross section contains a part of center line of the solenoid) Please let me know why we don't do like that. :)
