Explain meissner effect in superconductors
WebAs discussed in the Meissner effect that one of the conditions of the superconducting state is that Magnetic flux density (B) = 0 inside the superconductors that is the magnetic flux cannot penetrate inside the superconductor. But experimentally it is not so. The magnetic flux does not suddenly drop to zero inside the surface. The phenomenon of flux … WebSep 7, 2024 · The most talked about high temperature superconductor is YBa2Cu3O7-x or YBCO. It was the first superconductor discovered that had a T C above liquid nitrogen (77K) with a T C of 92K. It is commonly used to demonstrate the Meissner Effect in classrooms and a power cable was built out of it in New York.
