For a loop inside the hollow portion of the conductor, the current enclosed is zero until the loop is on the surface or inside the material of the conductor.
∴Binside=0
For any loop outside, current enclosed by the amperian loop is not zero, hence the magnetic field is non-zero.

Generally when current passes through a conductor(metals),the current flows around the conductor(metals)and not inside it.so the magnetic field will also act outside the metal
