Want to levitate? All you need are magnets, liquid nitrogen and superconductors.
Well, maybe not exactly. But if you want to make a model train levitate, those were the ingredients used in a new YouTube video from Earth Unplugged showcasing incredible levitation in slow motion.
In the video, Dr. Kei Takashina, a scientist of magnetic levitation from the University of Bath in the U.K., demonstrates in an experiment how magnetic levitation is used to propel Maglev trains, which are growing in popularity around the world. Dr. Takashina warns that the physics shown in the video is not an exact replica of the Maglevs, but both have levitation created by a magnetic field.
