Superconductor Hats

Description: A frozen superconductor, which is very cool

Description: 666

Description: The Meissner effect (also known as Meißner–Ochsenfeld effect) occurs when a superconductor reaches its supercondictivity state by being cooled below the transition temperature. It leads to an expulsion of the magnetic field, illustrated by the magnetic field lines (arrows) being excluded from the material. Choose this cute design if you love physics, electromagnetism or material science, because the future will be superconducting.
