For stars without suppressed modes (open circles) we can only derive an  upper limit to the field at the hydrogen-burning shell; above or below the shell the field could potentially be larger.   From Figure 4, we conclude that magnetic fields above $10 \, {\rm kG}$ are not present at the hydrogen-burning shell for stars below 1.1\msol when they are near the red giant luminosity bump (\numax\ $\sim50$\muhz\ ). $\sim50$\muhz\).  Assuming magnetic flux conservation from the hydrogen-core burning phase, this suggests that magnetic fields above $1 \, {\rm kG}$ do not exist within the inner cores of Sun-like stars. However, strong horizontal fields may still exist near the radiative-convective boundary of Sun-like stars because these fields are outside the core and cannot cause mode suppression when the star evolves into a red giant. %For stars with suppressed modes we derive the lower limit of how  %strong the field in the core [at least] needs to be for suppression to
