# Applying Biot-Savart Law to a superconductor

If I were to attempt to calculate the magnetic field produced by an infinite wire at a certain point, I would use Biot-Savart Law to approximate the magnitude of the field at point($P$) away form the wire. However, would the same equation become valid for a superconductor of both types I & II?

How would the Meissner effect alter the equation? If I consider the case of a large diameter copper wire of radius(r) Biot-Savart equtions:

$$B_p = \frac{\mu_0i}{2\pi R}$$

Where $R = L + r$, L being the distance of point $P$ away from the wire added by the wire's radius. In the case of a superconducting wire, Meissner's effect that's expelling the field from within the superconducting wire, would $r$ be irrelevant if the superconductor had a large diameter(or radius)?

Would that result to a stronger field at the same $L$ and the same current applied to both the superconductor & RT-conductor(copper)?
