History
- 1839 Earnshaw's theorem showed electrostatic levitation was impossible, later theorem was extended to magnetostatic levitation by others
- 1912 Emile Bachelet awarded a patent in March 1912 for his “levitating transmitting apparatus” (patent no. 1,020,942) for electromagnetic suspension system
- 1933 Superdiamagnetism Walter Meissner and Robert Ochsenfeld (the Meissner effect)
- 1934 Hermann Kemper “monorail vehicle with no wheels attached.” Reich Patent number 643316
- 1939 Braunbeck’s extension showed that magnetic levitation is possible with diamagnetic materials
- 1939 Bedford, Peer, and Tonks aluminum plate placed on two concentric cylindrical coils shows 6-axis stable levitation.
- 1961 James R. Powell and BNL colleague Gordon Danby electrodynamic levitation using superconducting magnets
- 1970s Spin stabilized magnetic levitation Roy M. Harrigan
- 1974 Magnetic river Eric Laithwaite and others
- 1979 transrapid train carried passengers
