Abstract
The root-mean square radius of the deuteron magnetic moment distribution,
r
Md
, is calculated for several realistic models of the
NN
--interaction. For the Paris potential the result is
r
Md
=2.312±0.010
fm. The dependence of
r
Md
on the choice of
NN
model, relativistic effects and meson exchange currents is investigated. The experimental value of
r
Md
is also considered. The necessity of new precise measurements of the deuteron magnetic form factor at low values of
Q
2
is stressed.
