Q. An infinitely long wire parallel to the x-axis is kept at π§ = π and carries a current I in the positive x direction above a superconductor filling the region π§ β€ 0 (see figure). The magnetic Β field Β π΅ββΒ Β inside Β the Β superconductor Β is Β zero Β so Β that Β the Β field Β just Β outside Β the superconductor is parallel to its surface. The magnetic field due to this configuration at a point (π₯, π¦, π§ > 0) is
