The Meissner effect is a defining characteristic of which state of matter?

Correct option is D

The correct answer is (d) Superconducting state

• The Meissner effect is a phenomenon observed in superconductors, where the magnetic field is expelled from the interior of a superconductor when it transitions into the superconducting state below a critical temperature.

• In the superconducting state, the material shows zero electrical resistance and exhibits the expulsion of magnetic fields. This behavior makes superconductors ideal for applications like magnetic levitation and high-efficiency power transmission.

Information Booster:

• Superconductivity: A state of matter where a material, typically a metal or an alloy, has zero electrical resistance and can conduct electricity with no energy loss, often at very low temperatures.

• Meissner Effect: The expulsion of magnetic fields from a superconductor when it is cooled below its critical temperature. This makes superconductors perfect for creating magnetic fields in applications like MRI machines and magnetic levitation trains.

• Applications of Superconductivity: Superconductors are used in technologies like high-speed trains, MRI scanners, particle accelerators, and quantum computing.

Additional Information:

• Insulating State: Insulators do not conduct electricity and do not exhibit the Meissner effect.

• Ferromagnetic State: In ferromagnets, the material retains magnetization, but the Meissner effect does not apply.

• Paramagnetic State: Paramagnetic materials are weakly attracted by a magnetic field and do not show the Meissner effect.
