# What is maximum magnetic field strength of SC magnet

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?

For reference -
from Wikipedia - http://en.wikipedia.org/wiki/Earth's_magnetic_field. Apparently some take the Earth's field at about 50 $\mu$T.

Intuitive posted a link to a list of records of "Magnetic Field of the Strongest Magnet".

which has a link to NATIONAL HIGH MAGNETIC FIELD LABORATORY - http://nmr.magnet.fsu.edu/facilities/45T_32mm_TLH.htm

In the case of high field pulsed magnets -

You are encountering the problem many of us have in deciphering things like this. If you look closely, a lot of these claims are meant for either a particular configuration, or a particular material. This is true, for example, in the Nb-Sn claim. They're not claiming that it is the largest ever magnetic field generated. So things like this can be confusing.

Unfortunately, you've asked this after I've started my vacation, so I do not have access to all the online libraries at work and can't go do a quick check on the highest field so far. But I would guess that continuous 45 Tesla claim would not be too far off. The record for pulse field, I don't know.
