When a superconducting material is placed in an external magnetic field below the critical temperature, it*1 pointEnhances the magnetic field linesDoes not influence magnetic field linesAttracts the magnetic field linesRepels the magnetic field lines
Solution
The correct answer is: Repels the magnetic field lines.
Here's why:
Superconductors are materials that can conduct electricity with zero resistance. This happens when they are cooled below a certain critical temperature.
When a superconducting material is placed in an external magnetic field, it exhibits a phenomenon known as the Meissner effect. The Meissner effect is the expulsion of a magnetic field from a superconductor when it goes below its critical temperature.
So, the superconducting material does not enhance, attract, or remain indifferent to the magnetic field lines. Instead, it repels them. This is a fundamental property of superconductors and is a direct result of their ability to carry current with no resistance.
