Another poster is looking for a 20T magnetic field or better, so I went looking for what has been reported as the maximum field strength for an SC magnetic field to date. However I found some contradicting claims.
Is there a refereeing organization or a reputable source from which to determine the actual maximum field strength so far achieved?
Well FSU's does beat LBL's, but NRIM's would exceed either. Are there anymore claims out there?
I had thought that 15T was about the max.

STA TODAY November 1999, http://www.mext.go.jp/english/news/1999/10/s991002.htmNational Research Institute for Metals (NRIM) of the Science and Technology Agency (STA) which had been constructing a high magnetic-field laboratory as a key center for high magnetic-field research succeeded recently in generating a magnetic field of 37.3 teslas (1 tesla = 10,000 gausses) in a steady-state by using a hybrid magnet. This success is expected to contribute to a remarkable progress in such areas as research on materials in high magnetic fields. The highest record sofar had been 36 teslas also attained by NRIM in 1995.
http://www.lbl.gov/Science-Articles/Archive/14-tesla-magnet.html (July 5, 2001)The team’s newest niobium-tin dipole electromagnet reached an unprecedented field-strength of 14.7 Tesla. This is more than 300,000 times the strength of Earth’s magnetic field.
http://www.research.fsu.edu/researchr/fall2003/departments/abstracts.html#superIn August, researchers at the National High Magnetic Field Laboratory's headquarters at FSU announced that they had set a new world record in the power of a special kind of magnet built with superconducting materials.
The device achieved a strength of 25 Tesla (a measurement of magnetic field strength), breaking a 20-Tesla barrier that had stood for more than 15 years. (A single Tesla is 20,000 times the strength of Earth's magnetic field; a small refrigerator magnet is typically one Tesla or less.) Early 2004.

from Wikipedia - http://en.wikipedia.org/wiki/Earth's_magnetic_field. Apparently some take the Earth's field at about 50 [itex]\mu[/itex]T.The strength of the field at the Earth's surface at this time ranges from less than 30 microteslas (0.3 gauss) in an area including most of South America and South Africa to over 60 microteslas (0.6 gauss) around the magnetic poles in northern Canada and south of Australia, and in part of Siberia.
