Magnetic Levitation Globe
Why can't we just levitate metal objects with a magnet at the right distance? Because, as a ferrous material nears a magnetic field, the force increases exponentially. This is described by what is called the magnetic inverse square law which states: Intensity1 / Intensity2 = Distance1 / Distance2.

What if you could travel from New York to Los Angeles in just under seven hours without boarding a plane? It could be possible on a Maglev train.
Maglev -- short for magnetic levitation -- trains can trace their roots to technology pioneered at Brookhaven National Laboratory. James Powell and Gordon Danby of Brookhaven received the first patent for a magnetically levitated train design in the late 1960s. The idea came to Powell as he sat in a traffic jam, thinking that there must be a better way to travel on land than cars or traditional trains. He dreamed up the idea of using superconducting magnets to levitate a train car. Superconducting magnets are electromagnets that are cooled to extreme temperatures during use, which dramatically increases the power of the magnetic field.
The first commercially operated high-speed superconducting Maglev train opened in Shanghai in 2004, while others are in operation in Japan and South Korea. In the United States, a number of routes are being explored to connect cities such as Baltimore and Washington, D.C.
Magnetic Levitation Floating Globe
In Maglev, superconducting magnets suspend a train car above a U-shaped concrete guideway. Like ordinary magnets, these magnets repel one another when matching poles face each other.
