Question

When a superconducting material is placed in an
external magnetic field it​

Answer 1

AnswerWhen a superconductor is placed in a weak external magnetic field H, and cooled below its transition temperature, the magnetic field is ejected from it and this phenomenon is called effect Meissner effect.

Answer 2

Answer:

The correct answer of this question is  superconductor is placed in a weak external magnetic field H, and cooled below its transition temperature, the magnetic field is ejected from it .

Explanation:

Given - superconducting material is placed in an external magnetic field .

To Find - Write when a superconducting material is placed in an external magnetic field.

The magnetic field is ejected from a superconductor when it is placed in a weak external magnetic field H and cooled below its transition temperature.

This magnetization is equal to and opposite to the magnetic field, cancelling out the magnetic field throughout the superconductor. As a result, the superconductor has a magnetic susceptibility of -1, indicating that it has complete diamagnetism.
