Unformatted text preview: of the Meissner effect. This also works because the magnet is very strong and small, which allows the levitation to counter the effects of gravity. When magnets were placed together, this repulsion became stronger as the magnet levitated higher. Part II: Loss of Electrical Resistance The pellet attached to the 4-pronged clip caused a constant fluctuation in voltage. Once the pellet was immersed in liquid nitrogen, the voltage was close to 0.00 mV. The electrical resistance disappeared. This is due to the flow of electrons typical of superconductors. Unlike normal conductors where the electrons collide in an electric current and energy is lost, the electrons in the superconductor flow without collisions....
