At temperatures near absolute zero, Bc approaches 0.142 T for vanadium, a type-I superconductor. The normal phase of vanadium has a magnetic susceptibility close to zero. Consider a long, thin vanadium cylinder with its axis parallel to an external magnetic field B⃗ 0 in the + x-direction. At points far from the ends of the cylinder, by symmetry, all the magnetic vectors are parallel to the x-axis. At temperatures near absolute zero, what are the resultant magnetic field B⃗ and the magnetization M⃗ inside and outside the cylinder (far from the ends) for (a) B⃗ 0=(0.130T)i^ and (b) B⃗ 0=(0.260T)i^?
