Sun-like stars are able to continuously generate a large-scale magnetic field through the action of a dynamo. Various physical parameters of the star are able to affect the dynamo output, in particular the rotation and mass. Using new generation stellar spectropolarimeters (ESPaDOnS@CFHT, NARVAL@TBL), it is now possible to measure the large-scale magnetic field of solar analogues (i.e. stars very close to the Sun in the stellar-parameter plane, including strict solar twins). From spectropolarimetric time-series, tomographic inversion of polarized Zeeman signatures allows us to reconstruct the field geometry and its progressive distortion under the effect of surface differential rotation. We detail the first results obtained on a sample of four main-sequence dwarfs, with masses close to 1 solar mass and rotation rates between 1 and 3 solar rotation rate.
