Question

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

Answer 1

Explanation:

There is a circular coil having N turns, the field produced is n times as a large as that produced by a single turn. It happens because the current in each circular turns has the same direction and the field due to each turn just adds up.
