Every coil is a closed circuit that is not in contact with an external power supply or any other coil. In the Indutrack system, Halbach arrays which are an arrangement of permanent magnets are installed on the bottom of the train which generates a magnetic repulsive field while the train is passing over the passive coils on top of the magnetic rail. Similar to Maglev trains, it also utilizes passive Electrodynamic Suspension involving the implementation of permanent magnets of Neodymium Iron Boron instead of superconducting magnets. This technology is much cheaper and simpler than Maglev train. The USA constructed a new technology of maglev system in order to get rid of expenditures required to construct a magnetic levitation train usually referred to as “Indutrack”.

Even though the maglev system is comprehensively reliable and tested, yet it is so costly to design as well as complex to construct and operate such a system. The guidance, propulsion, and levitation systems are all inserted inside the sides of the guide-way. In a maglev system, the phenomenon of superconductivity is adopted in order to attain zero electrical resistance and hence extremely powerful magnetic force. Recently, the maximum speed attained by magnetic levitation train is approximately equivalent to 603 kilometers per hour which were possibly adopted by using the Superconductor Electrodynamic Suspension (EDS) technology. Since such trains have no physical or mechanical contact as well as no friction is generated in the Maglev system, therefore these features make the magnetic levitation train feasible to attain high speeds. In such train, magnets are arranged inside the magnetic rails with the same poles along the direction of train movement and hence their movement depends on the magnetic field generated between the guideline and the vehicle. It utilizes non-contact magnetic levitation, propulsion, and guidance systems and is without wheels, axles, and transmission. In comparison with the traditional railroad vehicles, having a high-speed Maglev train does not have direct physical contact with the rails. From the discovery of the railroad industry, the magnetic levitation train is considered the first essential innovation in the field of the railroad industry. Nowadays Maglev trains are undeniably highly developed vehicles in railway technologies.
