Question

With the help of a labeled diagram, explain the distribution of magnetic field due to
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?
​

Answer 1

Answer:

The magnetic field lines due to a circular coil is shown in the given figure. At every point on a current carrying circular loop, the magnetic field is in the form of concentric circles around it. As we move away from it, the circles would become larger and larger. ... Therefore, the field due to these turns adds up.
