Frictionless magnetic levitating toy train

I envy anyone who gets to play with liquid nitrogen. This toy train example shows some of the neat abilities of magnetic levitation with superconductors.

The core of the bearings consists of a magnetic rail and super-conducting bulks, cooled to a temperature of -196C.

During the cooling process, the magnetic field of the rail will be written in the superconductors, which are positioned at a set distance from the magnetic rail.

This enables them to retain a set horizontal position in relation to the rail. Their super-conducting operational temperature is maintained in cryostats, initially through cooling in liquid nitrogen.
