A levitation project stands out at a science fair because nothing else on the table is doing it. The catch is that the best version needs liquid nitrogen, and the version that needs none is a different project with different...

This project levitates a small train on permanent magnets alone — no liquid nitrogen, no cryogenic handling, no special safety kit. That makes it one of the few levitation projects you can build and demonstrate in an ordinary classroom. If...

Ever wondered how Quantum levitation is possible? It’s all due to superconducting materials! These materials have special properties that allow them to conduct electricity without any resistance. When a magnet is placed near a superconducting material, the superconductor does two...

A superconductor cooled in liquid nitrogen will hang in mid-air above a magnetic track and glide along it with almost no friction — a real hoverboard, at desk scale. It also makes an unusually strong science fair project, because unlike...

Superconductivity introduces one of the most technically difficult challenges for physicists – designing a measurement setup that is sensitive to very low (and zero) voltages and resistances and to high voltages and resistances at the same time. Below we give...

Qualitative Experiment steps: Quantum Levitation is the stable levitation and suspension of a superconductor in a surrounding magnetic field. It is actually the result of two separate phenomena: Meissner effect - the repulsion of magnetic fields from the superconductor body...
