  I review ongoing efforts to understand the incidence of magnetism in
intermediate-mass stars that are different from the magnetic Ap stars. This
includes the search for magnetic fields in chemically peculiar stars of the Am
and HgMn types as well as in normal A and late-B stars. I discuss different
techniques for detection of weak stellar magnetic fields and present a critical
evaluation of the recent magnetic detections in non-Ap stars. Special attention
is given to the magnetic status of HgMn stars and to the discovery of weak
polarization signatures in Sirius and Vega.
