The utility model discloses a three-in-one automatic-control high-temperature superconduction magnetic levitation teaching aid which comprises the components of a fixed bracket, a magnetic rail, linear motors, a levitation trolley and a power controller. The fixed bracket comprises a supporting rod and a suspension which is fixedly connected with the upper end of the supporting rod. The magnetic rail is made of a magnet-conductive metal and is Mobius-strip-shaped. The magnetic rail is connected with the suspension through a drawing cable. Two side surfaces of the magnetic rail are respectively provided with a permanent magnet, thereby forming a magnetic rail of the levitation trolley. The levitation trolley levitates on the magnetic rail. Two sides of the magnetic rail are provided with motor brackets. The linear motors are symmetrically mounted on the motor brackets at two sides of the magnetic rail. Simultaneously each motor bracket is provided with a photoelectric switch. The power controller is connected with the photoelectric switches and the linear motors. The three-in-one automatic-control high-temperature superconduction magnetic levitation teaching aid has advantages of simple structure and small volume. The three-in-one automatic-control high-temperature superconduction magnetic levitation teaching aid has three demonstrating effects of levitation, suspension and side hanging. The three-in-one automatic-control high-temperature superconduction magnetic levitation teaching aid can perform acceleration, speed reduction test and demonstration.
