Claim Text:
1. A drain stopper assembly for a drain pipe defining an internal drain passage and having an upper entrance leading into the drain passage, said assembly comprising: a stopper disposed for movement with respect to the upper entrance toward and away from a sealed condition to prevent the passage of liquid into the drain passage, said stopper including a stopper magnet producing an electromagnetic field; a driver magnet situated external to the drain pipe exterior, said driver magnet producing at least one electromagnetic field that generates a repellant electromagnetic field with respect to said stopper magnet, and said driver magnet swings in a compound trajectory comprised of lateral and longitudinal displacement toward said stopper magnet so that said electromagnetic fields interact in a non-linear relationship along a curved path of motion to induce movement of said stopper away from said sealed condition.
