  We investigated the form factors of the nucleon associated with the nonet
vector current in the framework of the generalized Yabu--Ando approach to the
chiral soliton of the Nambu--Jona--Lasinio model. We introduce a variational
parameter to improve the predictions for the baryon mass splittings and, in
addition, we take into account $1/N_c$ rotational corrections to accommodate
the empirical isovector magnetic moment of the nucleon. We find that the
strange magnetic moment lies between -0.05 and 0.25.
