Q. An infinitely long wire parallel to the x-axis is kept at ๐ง = ๐ and carries a current I in the positive x direction above a superconductor filling the region ๐ง โค 0 (see figure). The magnetic field ๐ตโโ inside the superconductor is zero so that the field just outside the superconductor is parallel to its surface. The magnetic field due to this configuration at a point (๐ฅ, ๐ฆ, ๐ง > 0) is
