 \item
 From the derivation of the Ginzburg-Landau theory, we get the following expression for the supercurrent $\vec{J_s}$:
 \[
-	\vec{J_s} = -\frac{2e\bar{h}n_s}{m}(\nabla\theta + \frac{2e\vec{A}}{\bar{h}})
+	\vec{J_s} = -\frac{2e\hbar n_s}{m}(\nabla\theta + \frac{2e\vec{A}}{\hbar})
 \]
 Using the rigid gauge, we set $\theta = 0$.
 Next, we can equate the previously found supercurrent for our foil to the Ginzburg-Landau found one and reorder to find $\vec{A}$:
