Answer 1

AnSwEr

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 because the current in the coil any any point is same and the field due to each turn just adds up.

Answer 2

Answer:

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