In ampere circuital law, ∫B.dl = μo inet
i includes current "only passing through the loop "
also B is the net mag field at any point "all to any current anywhere"
now look at the pic.
In A, it is very easy to find field using ampere law ... its μi/2πr
Also if in B is you apply the law, B is again μi/2πr ... how is this possible
its like the external current doesn't make any difference!
Plz explain me this !
