If a current i ampere flows in a long straight thin walled tube, then magnetic induction at any point inside the tube is

(A) : A current I flows along the length of an infinitely long, straight, thin-walled pipe. Then the magnetic field at all points inside the pipe is zero. (R) : The whole pipe carrying current can be supposed to be made of thin rings. The magnetic field on the axis of the ring is is zero.
