Magnetic fields play a key role in the pulsations of rapidly oscillating Ap (roAp) stars since they are necessary ingredient all pulsation excitation mechanisms proposed so far. This implies that proper understanding seismological behaviour roAp requires knowledge their magnetic fields. However, not well studied. Here we present new results measurements mean longitudinal field 14 obtained from low resolution spectropolarimetry with FORS 1 at VLT.
