Is There a Word ???

Been trying to think of words that best describe what happens when Alexis sees her mother--- First thought, "magnetism"-- true there is a force of attraction impossible to resist, but it isn't an invisible force field-- nay on the contrary, it's visible, tangible, and visceral!! Isn't just the "eyes light up" kind of magic, no, every cell in body becomes electrified, hands and feet shake, squeals of potential pleasure emanate from wide open expectant mouth---- heaven and earth are powerless to resist the gravitational, autogenous, force of outreached hands- all four of them!! Then, pure bliss, as her little squirming body settles and nestles into her mother's safe harbour-- and she looks back at me--- a little smug, satisfied, "hmph-- I'm where I belong!"
