Zusammenfassung:The present utility model relates to a magnetic swing. The magnetic swing comprises a pedestal, a swing rack is arranged on the pedestal, two hanging ropes are arranged on the swing rack, a swing chair plate is connected between the two hanging ropes, a first magnet is connected below the swing chair plate, the pedestal is provided with a second magnet corresponding to the first magnet, magnetic poles of the first magnet are constant with those of the second magnet, and the first magnet is close to the second magnet as possible. When the magnetic swing is made, the fact that the swing chair plate is swung without being driven by power can be observed, thus students can understand that the swing chair plate is swung as same magnetic poles repel. Through making the magnetic swing, students can have a deeper understanding and memory of the principle that like poles repel and opposite poles attract.
