One of the key properties of a superconductor is that it is repelled by a magnetic field and hence floats above it, in a process known as quantum levitation. In a final-year project of the Singapore Polytechnic School of Mechanical & Aeronautical Engineering, the students built a hoverboard strapped to a box containing 6 pieces of YBCO discs. Below the box were 60 pieces of neodymium N50 magnets secured tightly together. The box was filled with liquid nitrogen until the discs became superconductors. When levitation occurred, gym weights were carefully placed on the hoverboard until the gap diminished. A total of 70.9 kg of weights was recorded. The experiment was demonstrated on 17 Nov 2017 by Leon Kwang, Amos Ng, Chen Xiao Wei, Thant Zaw Aung and Lew Lin, under the guidance of FYP supervisor Leong Ying Wei.
