Explain with the help of a labelled diagram the distribution of magnetic field due to a current through a circular loop. Why is it that if a current carrying coil has n turns the field produced at any point is n times as large as that produced by a single turn?

Even in current carrying loop, the is obeyed. According to the rule, Assume that you are holding a current-carrying straight conductor in your hand such that the thumb points towards the direction of the . Then your fingers will wrap around the conductor in the direction of the .
This shows that the magnetic field lines are present . But the circular shape of conductor means that field lines at of the loop appear to be making ring around the periphery of the loop. This looks like small ring looping around big ring.
If the number of turns of the coils increases, the magnetic field . Therefore the strength of the magnetic field with number of turns in a coil.
