    Shield low-frequency magnetic fields, but not high-frequency ones

    I am wondering if it is possible to shield strong (1 Tesla) DC magnetic fields with high attenuation factor (10^4 or better) WITHOUT also shielding AC magnetic fields above frequencies of ~10kHz. I have looked at mu-metal, which as far as I can tell shields DC but also AC fields to some...
