    "abstract": "We study the response of the nucleon, as a system of three bound\n(constituent) non relativistic quarks, to external (quasi static) electric and\nmagnetic fields. The approach, based on a sum rule technique, is applied to a\nlarge class of two and three-body interquark potentials. Lower and upper bounds\nto the electric polarizability and para-magnetic susceptibility are explicitly\ncalculated within a large variety of constituent models and their values\nrelated to the features of the interquark interaction picture. The r\\^ole of\nthree-body forces is investigated in details as well as the effects of SU(6)\nbreaking terms in the potential model. Our results can be used to extract the\nmesonic contributions to the static polarizabilty and susceptibility. The quark\ndegrees of freedom give a quite sizeable contributions to both and the meson\ncloud accounts roughly for 30% and 60% of the electric proton and neutron\npolarizability respectively. The quark contribution to the paramagnetic\nsusceptibility is even higher and the mesonic effects are rather uncertain.",
