  N-d elastic scattering is studied at different energies using one of the
modern NN interactions, the Argonne v_{18} which explicitly includes the
magnetic moment interaction between two nucleons. This interaction, which has
been often neglected in the description of the few-nucleon continuum, produces
sizable modifications in some elastic observables. Its effects, as well as
those produced by the Coulomb potential, are analyzed as a function of energy.
The magnetic moment interaction produces appreciable effects in $p-d$
scattering at low energies butthey are very small above 10 MeV. Above 65 MeV
Coulomb effects can be observed only in specific observables as for example
$T_{21}$.
