SUMMARY:Acoustic oscillations and dynamo action in giants
DESCRIPTION:The role of the magnetic field in determining the angular momentum  transport in stellar interior is still an open issue. Acoustic oscillations are directly affected by the presence of a large-scale magnetic field but their study can provide fundamental information on the properties of the magnetic fields in solar-like stars. As an example the case of  EK Eridani\, a slowly rotating\, overactive G8 giant\, will be presented.  Moreover the possibility to use asteroseismology to solve the  long-lasting mystery on the origin of magnetic fields in Ap stars will be discussed.
