Summary

A HIGH CRITICAL TEMPERATURE SUPERCONDUCTING LEVITATION BEARING DRIVEN BY AN OPTICALLY SWITCHED SOLENOID IS DESCRIBED. THE BEARING USES FLUX PINNING IN THE NEW HIGH CRITICAL TEMPERATURE SUPERCONDUCTORS FOR STABILITY. A SIMPLE LIQUID NITROGEN SUPPLY SYSTEM IS DESCRIBED THAT GREATLY IMPROVES THE EASE WITH WHICH HIGH CRITICAL TEMPERATURE SUPERCONDUCTORS CAN BE MAINTAINED AT 77 K FOR EXTENDED PERIODS OF TIME IN SMALL STYROFOAM DISHES. A FORCE VERSUS HEIGHT CURVE IS GIVEN AND IS USED TO DETERMINE THE DESIGN LIMITS OF THE LEVITATION BEARING.
