Physics Experiment on Instagram: "The Meissner effect is a fundamental property of superconductors, where a material expels all magnetic fields from its interior when it transitions into the superconducting state below a critical temperature. This effect was discovered by Walther Meissner and Robert Ochsenfeld in 1933. Unlike perfect conductors, which can trap magnetic fields, superconductors actively repel them, resulting in a magnetic field of zero inside the material. This causes phenomena li
