Magnetic levitation of trains by means of normal conductive electromagnets

It has been generally believed that the magnetic levitation of trains of the induction-repulsion type needs large ampere turn on the train magnets, and only superconductive magnets make the magnetic levitation feasible. However, the magnetic levitation becomes feasible also with the normal conductive electromagnet if the iron magnetic path is properly provided. An experimental example has been investigated.
