What is the characteristic magnetic field profile of a Pearl vortex in a thin film of type-II superconductor?

A. It has a very short range interaction and diverges as 1/r^2 near the center
B. It diverges sharply as 1/r at short distances and decays slowly like 1/r^2 at long distances
C. It remains constant at all distances from the center
D. It diverges as log(1/r) near the center and decays slowly at long distances
