Analyse information to explain why a magnet is able to hover above a superconducting material that has reached the temperature at which it is superconducting

  • Works by Meissner effect - expulsion of magnetic field during transition to superconducting
  • In this state, the super conductor does not allow external magnetic field inside of it.
  • Bringing a magnet near produces eddy currents which create an opposing magnetic field to stop magnetic field coming in
  • This opposition results in levitation of the magnet
