A circular wire of diameter D lies on a horizontal table and carries a current I

Question

A circular wire of diameter D lies on a horizontal table and carries a current I. In the figure point A marks the center of the circle and point C is on its rim.

A) Find the magnitude of the magnetic field at point A. (express your answer in terms of the variable I,D and (u0 and pi).

C) The wire is now unwrapped so it is straight, centered on point C, and perpendicular to the line AC, but the same current is maintained in it. Now find the magnetic field at point A.(express your answer in terms of the variable I,D and (u0 and pi).
