A constant direct current of uniform density j is flowing in an infinitely long cylindrical conductor. The
conductor contains an infinitely long cylindrical cavity whose axis is parallel to that of the conductor and
is at a distance i from it. What will be the magnetic induction at a point inside the cavity at a
distance i from the centre of cavity?
