Chapter 15, Problem 15F.5AE

Interpretation Introduction

Interpretation:

The highest magnetic field at which superconductivity can be maintained at 6K has to be calculated.

Concept Introduction:

The highest magnetic field at which superconductivity can be maintained at particular temperature T can be calculated as follows,

  $H_c\left(T\right)=H_c\left(0\right)\left(1-\frac{T^2}{T_c^2}\right)$

Where,

$H_c\left(T\right)=$ highest value of magnetic field that can be applied

$H_c\left(0\right)=$ critical value of magnetic field above which super conductivity looses

$T=$ temperature

$T_c=$ critical temperature
