The degree thesis is intended to study the principle of electromagnetic fields. The principle of rotating magnetic field occurred. The occurrence of electromagnetism The occurrence of induced voltage of electromagnetic fields and apply the knowledge gained from the study on building model trains floating magnetic energy. Based on the principle of generating electromagnetic fields causing permanent magnetic boost next to the BTS sky train, the float. The movement of the floating magnet power rail or a combination driven to create a rotating magnetic field principles. To achieve strong induction of electromagnetic fields Make model trains power magnetic float can move.
