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 B? 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.

Part B

What is the direction of the resultant magnetic field B? inside the cylinder for this case?

What is the direction of the resultant magnetic field inside the cylinder for this case?

in the +x-direction
in the ?x-direction
perpendicular to the x-axis
the field is zero
Part C

What is the magnitude of the resultant magnetic field B? outside the cylinder (far from the ends) for this case?

Part E

What is the magnitude of the magnetization M? inside the cylinder for this case?

Part G

What is the magnitude of the magnetization M? outside (far from the ends) the cylinder for this case?
