Question

1) With the help of a labelled diagram, explain 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? ​

Answer 1

• At every point of current carrying circular loop, the concentric circles representing the magnetic field around it becomes larger and larger .$\:$

• At the center of the loop, the field appears as a straight line .

• The magnetic field produced by current-carrying circular wire at a given point depends on :

• There is a circular coil having N turns .

• It happens because the current in each circular turns has the same direction
