Magnetic levitation, or maglev, is a technology that uses magnetic forces to lift and propel objects without physical contact. This phenomenon occurs when like poles of magnets repel each other, allowing trains, for example, to float above tracks, reducing friction and enabling high-speed travel. Maglev systems are not only efficient but also environmentally friendly, as they can operate on renewable energy sources. Countries like Japan and China have developed advanced maglev trains, showcasing the potential of this technology for future transportation solutions.
