Magnetic levitation - Science Experiment | Technology Innovation

Magnetic levitation, whether in a science demo or a high-speed train, relies on the same core idea: using magnetic fields to fight gravity. Magnets can repel or attract without contact, and with the right setup, they can suspend objects in mid-air. The real challenge is stability. Maglev trains solve this using electromagnets and sensors that constantly adjust the magnetic force, allowing the train to float smoothly just above the track. This system removes friction and enables speeds over 600 k
