Superconducting Magnetic Levitation Model Train

Superconducting Magnetic Levitation Model Train from the IFW Dresden, Germany. It is cooled with liquid nitrogen. The core is a super conducting material which conducts electric current without any resistance at temperatures below minus 180 degrees Celsius (minus 292 degrees Fahrenheit). In this state it can trap magnetic fields. The resulting magnetic forces cause not only the levitation but precision control above the rail, which is made of conventional magnetic material.
