An electromagnetic rocking chair is disclosed. The electromagnetic rocking chair includes a fixing part, a moving part being moveable relative to the fixing part, at least two electromagnets disposed on the fixing part, and at least one permanent magnet disposed on the moving part. When the moving magnet moves to a position over the fixed magnet, the fixed magnet is electrified to produce repulsion forces due to homopolar repulsion, whereby the repulsion forces and the inertial force generated during the course of movement of the moving magnet can move the electromagnetic rocking chair smoothly. |
