WebElectromagnetic propulsion ( EMP) is the principle of accelerating an object by the utilization of a flowing electrical current and magnetic fields. The electrical current is used to either create an opposing magnetic field, or to charge a field, which can then be repelled. WebThe system is based on the hydrogen proton exchange membrane (PEM) fuel cells. The fuel cell technology is applicable to high and low voltage, as well as AC and DC power systems, and can be used in combination with batteries or engines. The system can be fully hydrogen-electric or integrated as part of a hybrid power system. WebA system called electromagnetic suspension suspends, guides, and propels the trains. A large number of magnets provide controlled tension for lift and propulsion along a track. Maglev trains do not need an engine and, therefore, produce no emissions. They are faster, quieter, and smoother than conventional systems. north easton dental associates
