Survey of basic magnetic levitation research in Erlangen

A short survey of the basic research - theoretical and experimental - that is being done at the Research Laboratories of Siemens AG in Erlangen on various basic and hybrid levitation systems is given. Along with the digest of the so far published work, some new results on difference flux system, hybrid normal-null flux system with a T-shaped track and a simple hybrid ferromagnetic null flux system are also included.
