An implant system places magnetic structures in or on tissue that develop a magnetic repelling force between a soft palate a posterior pharyngeal wall. The magnetic repelling force has a magnitude F-mag, where F-mag=f (F-sep, F-nat), and where F-sep is a force required to separate soft palate tissue from pharyngeal wall tissue during sleep, and F-nat is a force exerted by native muscle on the soft palate during swallowing and/or drinking and/or speech. In another embodiment, a palate implant uses attractive magnetic force to keep the airway open.
