Magnetic field inside a vortex.

Click For Summary
SUMMARY

The discussion centers on the calculation of the magnetic field inside a vortex, specifically estimating a vortex size of 10-35 nm and deriving a magnetic field value of approximately 6.5-0.3 T using the magnetic flux quantum. Participants express concerns regarding the validity of this value, questioning whether such high magnetic field strengths are typical for vortex fields. The consensus indicates that while vortex fields can reach several tesla, the calculated value may be unexpectedly large and warrants further investigation.

PREREQUISITES

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?
 
Physics news on Phys.org
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.
