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?

    I had thought that 15T was about the max.

    For reference -
    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.

    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.
