Soorten supergeleiders

When a permanent magnet is placed over any type of superconducting material, the magnet gets repelled and levitates in a stable position due to the Meissner effect. Superconductors are categorized into Type I and Type II groups based on their behavior and characteristics.

Type I superconductors act as conductors when operated at room temperature. However, when cooled below the critical temperature, the molecular movement inside the substance is reduced, allowing the current to flow as freely as possible.

They typically consist of pure metals like mercury, zinc, aluminum, lead, etc., and fully obey the Meissner effect while having a low critical magnetic field.

Type-II superconductors exhibit an intermediate phase of mixed ordinary and superconducting properties at intermediate temperatures and fields above the superconducting phases.

They typically comprise elemental niobium, vanadium, technetium, and metal alloys or complex oxides.

Type-II superconductors partially obey the Meissner effect and have two critical magnetic fields.
