• Object suspended in air by magnetic force – excellent visual impact
• Controller design to maintain stability
• Up-down position setting by reference control

Magnetic Levitation, lifting of objects under the influence of a magnetic field, has numerous application including some advance locomotives designed on the repulsive force of a magnet. The present unit, base on the attractive force of an electromagnet, is inherently unstable. There is no way to keep an iron object suspended in air by manually adjusting the current in the electromagnet. Even a feedback control with forward path gain control alone is ineffective. These facts are brought out by studying and experimenting with the dynamics of the system. The next task consists of the design of suitable controller and implementing the same to achieve the desired objective. A sound knowledge of MATLAB and its availability should be highly desirable, though not essential, for the conduct of this experiment. The basic theory, analysis and sample calculation are described in the accompanying literature.
