We have identified 7 new magnetic DA white dwarfs in the Early Data Release
of the Sloan Digital Sky Survey. Our selection strategy has also recovered all
the previously known magnetic white dwarfs contained in the SDSS EDR,
KUV03292+0035 and HE0330-0002. Analysing the SDSS fibre spectroscopy of the
magnetic DA white dwarfs with our state-of-the-art model spectra, we find
dipole field strengths 1.5<=B_d<=63MG and effective temperatures
8500<=Teff<=39000K. As a conservative estimate, we expect that the complete
SDSS will increase the number of known magnetic white dwarfs by a factor 3.Comment: 7 pages, 4 figures, accepted for publication in Astronomy &
