2. As shown below, An infinitely long conducting wire lying along z-axis and a rectangular loop of conducting wire at a distance "d" from the z axis form a coupling system. The permeability of the medium changes with the distance from the z-axis as (r) = H, (n+2)r"*2 where n is the last digit of your own student number. Find the mutual inductance of this system if d = nb. n=3 = 4,(n+2)r"*2 a d b
