How does the maglev train work?

Here at the ILK Dresden, we work experimentally down to around -271 °C. Very, very low temperatures are needed, for example, to levitate magnets. We will show you how a magnetic levitation train works, which is cooled with liquid nitrogen or helium (-196 °C).

Start 17:00 o'clock

End 23:00 o'clock

description

The electrical resistance of a superconductor disappears below the critical temperature and it becomes an ideal conductor. We will show you how a magnetic levitation train cooled with liquid nitrogen or helium (-196 °C) works. By the way: The ILK Dresden has developed cryostats for cooling sensors with liquid nitrogen or helium, which can be used in a variety of ways. In particular, metal-free GRP cryostats with special properties have been developed for cooling superconducting current limiters and SQUIDs (highly sensitive magnetic field sensors), which can also be designed as pressurised devices.
