Question: Q: Superconductors expel a magnetic field from their interior. what is this phenomenon known as? Read this paragraph and choose the correct option from the provided answers: Summary Superconductors are solids that at low temperatures exhibit zero resistance to the flow of electrical current, a phenomenon known as superconductivity. The temperature at which the electrical resistance of a substance drops to zero is itssuperconducting transition temperature (Tc). Superconductors also expel a magnetic field from their interior, a phenomenon known as the Meissner effect. Superconductivity can be explained by the BCS theory, which says that electrons are able to travel through a solid with no resistance because they couple to form pairs of electrons (Cooper pairs). Hightemperature superconductors haveTc values greater than 30 K. Choices: - weissenberg effect - eibner effect - lauer effect - meissner effect A:
Answer: meissner effect
