Question

what is the effect of an external magnetic field on the superconducting state of a material? What do u mean by flux reflection​

Answer 1

Answer:

Explanation:

As the temperature or the external magnetic field is increased, the normal regions are packed closer together. The vortices feel a force when current flows, and if they move, the superconducting state is lost.

Flux describes any effect that appears to pass or travel (whether it actually moves or not) through a surface or substance. A flux is a concept in applied mathematics and vector calculus which has many applications to physics. For transport phenomena, flux is a vector quantity, describing the magnitude and direction of the flow of a substance or property. In vector calculus flux is a scalar quantity, defined as the surface integral of the perpendicular component of a vector field over a surface

Answer 2

The effect of an external magnetic field on a superconducting state of a material is called superconductivity.

• When a superconducted material is introduced into an external magnetic field, it produces an equal and opposite magnetic field of its own.
• Electric current in a superconducting loop has been observed to last for years and theoretically, can last forever.
• Flux is the total number of magnetic lines passing through a given closed area. When a current is induced in the magnetic field it opposes the initial magnetic flux.
