AC magnetic field dependence of fundamental and third
harmonic AC susceptibilities ($\chi_1''$, $\chi_3'$ and
$\chi_3''$) were measured for two Nb-Ti multifilamentary
wires with different filament diameters to investigate the
effect of the reversible motion of fluxoids. The results
agree approximately with the prediction of the Campbell
model in which the reversible motion of fluxoids is
treated. The critical current densities estimated from AC
susceptibilities and that from the hysteresis of DC
magnetization are compared. The large difference of the
critical current density at high magnetic field from two
methods seems to be explained by the distribution of the
filament size.
