Magnetic field inside a vortex.

[nbo10]

Hi all,
I have a dumb question on the field inside of a vortex. A simple claculation using the magnetic flux quantum and estimating the vortex size to be 10-35nm. You get a magnetic field value of ~6.5-0.3 T. Which at first thought seems strange, maybe I'm not thinking of something correctly. Does anyone have any thoughts?

Vortex fields of the order of a few tesla seem to be right. What's the problem with it ?

The number seems large. I think I would have remember values that large from muon spin measurements.
