why can't we get the expression for the magnetic field due to a long current carrying straight conductor by applying ampere circuital law even though it is applicable everywhere.(note:- wire is not of infinite length)

Thus, Ampère's circuital law can be written: The line integral of the magnetic field around some closed loop is equal to the mew not times the net current which pass through the loop.

it is applicable only on closed circuits
so how we get the expression for infinitely long wire using ampere circuital law
we do get an expression for the infite long current carrying wire using ampere circuital law
which is B= u i / 2πr
bro tell me
no idea
can i answer this
Yup sure
during solving the derivation for the limitedly long wire we have to consider all the cosine angles of all the wires of the loop of which it is a part which makes the calculation much more complex
that's why we can't get an expression for it using ampere circuital law
