The 72 cm diameter Magnetic Levitation kit is perfect for large audience demonstrations at science museums, science fairs and student classes. The circular frictionless motion never ceases to amaze.
The kit is supplied with large and medium Quantum Levitators, which can be levitated simultaneously in a double levitation configuration. Both suspension below the track and levitation above it can be demonstrated. A handheld magnetic device (MagLev Starter Kit) is included for a complete experience. Please note that this product requires liquid nitrogen.
How It Works
These high-temperature superconductors conduct electricity without energy loss when cooled to the temperature of liquid nitrogen (77 K). Because a superconductor expels external magnetic fields by forming surface currents, which cancels the external field, it will levitate above a magnet.
