  We present the BinaMIcS project, its goals and the first BinaMIcS
spectropolarimetric observations obtained with Narval at TBL and ESPaDOnS at
CFHT: dedicated time-series for targeted hot and cool close double-line
spectroscopic (SB2) binaries and a survey of hot close SB2 binaries. The very
first results are also presented. In particular, our first survey observations
seem to show a lack of magnetic fields in hot close binaries compared to single
stars.
