During the 2867 Steins flyby of the ROSETTA spacecraft on September 5, 2008 magnetic field measurements have been made with both the RPC orbiter magnetometer and the ROMAP lander magnetometer. These combined magnetic field measurements allow a detailed examination of any magnetic signatures caused either directly by the asteroid or indirectly by Steins' different modes of interaction with the solar wind. Comparing measurements with simulation results show that Steins does not posses a significant remanent magnetization. The magnetization is estimated at less than 10(-3) A m(2)/kg. This is significantly different from results at 9969 Braille and 951 Gaspra.
