Levitation
• Full Scale
• Superconductors at Low Temps
• Induction Coils
• More Weight = Lift at Lower Speed
7Tuesday, January 27, 2009

Levitation
• Model Scale
• Permanent Magnets
• Weight-Sensitive
• More Weight = Closer to Track, Less Stable

Stabilization
• Carriage Must Remain on Track
• Inherently Unstable
• Manual or Automatic Compensation
• Test Different Configurations
