Wilson lines in N=4SYM can be computed in terms of branes carrying electric
flux, i.e. F-strings dissolved in their worldvolumes. It is then natural to
think that those configurations are the effective description of strings
expanding due to dielectric effect to D-branes. In this note we explicitly show
this for a class of such configurations, namely those dual to Wilson lines
either in the symmetric or in the antisymmetric tensor product of fundamentals.Comment: Final version to appear in Nucl.Phys.B. Cites adde
