“Magnetic levitation in physics is called the Meissner effect. When some materials go below a certain temperatures, called the critical temperature, they become a superconductor. In this state, magnetic lines cannot penetrate into the material. When you put a superconductor on a magnetic area, the field lines are repelled by the superconductor so they surround this material and a state of locking happens. It will levitate on the magnetic area.” – Amir Sajad Esmaeily, CRANN
