Magnetic fields play a role in almost all stages of stellar evolution \citep{Landstreet_1992}.  Most low-mass stars, including the Sun, show surface fields that are  generated by dynamo processes in their convective envelopes \citep{Parker_1955}. \citep{Parker_1955,Donati_2009}.  Intermediate-mass stars do not have deep convective envelopes \citep{Kippenhahn_1990}, yet 10\%  exhibit strong surface fields that are presumed to be residuals from the stellar  formation process \citep{2008CoSka..38..443P}. These stars do have convective cores that might produce
