Question
Exercise 29.45 At temperatures near absolute zero, Be approaches 0.142 T for vanadium, a type-1 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 extemal magnetic field Bo 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. Part A temperatures near absolute zero, what is the magnitude of the resultant magnetic field B inside the cylinder for Bo (o.130T)i? My Answers Give Up Correct Part B What is the direction of the resultant magnetic field Binside the cylinder for this case? in the +z-direction in the z-direction perpendicular to the ar-axis the field is zero Submit My Answers Glve UpExplanation / Answer
B.
The magnetic field less than the critical field, direction of resultant magnetic field is zero.
D.
Direction of magnetic field outside the cylinder is along B0, that is in the +ve x direction.
F.
Direction of magnetization inside the cylinder is -x direction.
H.
Direction of magnetization outside the cylinder is zero.
