Abstract

Measurements of magnetic fields in the solar corona are needed toimprove our understanding of structures, dynamics and heating of the corona and of the acceleration of the fast and slow modes of the solar wind expending into the heliosphere.However, those measurementsare very difficult andstill very scarce.I revue the main methods proposed to access the direction and the strengthof the coronal magnetic field and discuss what seem the main avenues toimprove its determination in the future.
