Stars above $1.6 M_\odot$ show a 50-60\% suppression rate, much larger than  can be accounted for by the up to 10\% of A-type stars known to show strong surface fields,  \citep{2008CoSka..38..443P}. This shows  that the previously known magnetic A stars detected through their surface  fields are only the tip of the iceberg and a much larger fraction of A  stars host strong magnetic fields hidden in their core.   %The rapid fractional increase reaching 50-60\% for stars above 1.6\msol, coincides  %with the mass beyond which about 10\% of hydrogen-core burning A-stars are  %known to show strong magnetic fields on the surface [Power2008].   %[The large fraction of suppressed stars above 1.6\msol\ coinsides with  %the masses of A stars, of which up to 10\% are known to have strong  %surface fields[REFS].]   %This further supports that the suppression arises from a magnetic field.  %Even more interesting, it shows that the previously known magnetic A   %stars detected through their surface fields are only the tip of the  %iceberg and a much larger fraction of A stars host strong magnetic fields  %hidden in their core.   %, than anticipated purely from their observable surface fields.   In Figure 4, we show the observed \numax\ and inferred mass of all the  stars superimposed on a contour plot of theoretically predicted magnetic field strengths
