Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.If the loop is vertical Field lines are perpendicular to your dl vector thus cos90 = 0.
If the loop is horizontal the B.dl value cancels its counterpart
Didn't understand what u said in the second line
Notice since dl in opp direction generates negative of its counterpart
@PeriodicTable ji
Yes yes thanks
