is statement mein sayad
B.2pir=μi
coz u gotta select crrct amperian loop of uniform charg distrinuition effect to get gud results
A wire of length l has current i
apply amperes law
∫B.dx=μi
B.2pir=μi
B=μi/2πr ...(:P same as of infinite wire.)
But we know it should be
B=μi(sinα+sinβ)/4πr
Explain what is wrong..
