Supernova 1987A in the Large Magellanic Cloud has proven a unique laboratoryto investigate particle acceleration in young supernova remnants. Here wereport the first detection of linear polarization of the supernova'ssynchrotron emission from imaging observations at frequencies spanning from 20to 50 GHz, carried out with the Australia Telescope Compact Array betweenOctober 2015 and May 2016. The direction of the radio polarization, correctedfor Faraday rotation, points to a primarily radial magnetic field across theinner ring, encompassing both the reverse and forward shocks. The magneticfield strength peaks over the high-emissivity eastern sites, where efficientcosmic ray acceleration likely takes place under quasi-parallel shocks at highMach numbers. The mean fraction of polarized emission in the brightest sites is$2.7\pm0.2\%$ at 22 GHz and $3.5\pm0.7\%$ at 44 GHz. In the inner remnant,non-radial components of the polarized emission appear to be more prevalent.However, the low significance detection in the central regions limitsinterpretation.
