In: Physics

A long straight cylindrical shell has an inner radius Ri and an outer radius R0.

A long straight cylindrical shell has an inner radius Ri and an outer radius R0. It carries a current I, uniformly distributed over its cross section. A wire is parallel to the cylinder axis, in the hollow region (r < Ri). The magnetic field is zero everywhere outside the shell (r > R0).

We conclude that the wire: 

A) is on the cylinder axis and carries current I in the same direction as the current in the shell 

B) may be anywhere in the hollow region but must be carrying current I in the direction opposite to that of the current in the shell 

C) may be anywhere in the hollow region but must be carrying current I in the same direction as the current in the shell 

D) is on the cylinder axis and carries current I in the direction opposite to that of the current in the shell 

E) does not carry any current.
