How magnetic levitation lifts and propels high-speed maglev trains

‘Maglev’ is a portmanteau of ‘magnetic levitation’. Instead of running on wheels, maglev technology uses strong magnetic fields to lift the train and move it forward. Since the train floats above the track, there is no rolling friction during normal operations, nor are operations affected by inclement weather, like rain or snow. The result: the...
