if XY is moved horizontally in any direction, no magnetic field lines will be cut therefore no change would be observed on the pointer.
However, if XY is moved up and down repeatedly at right angles to the magnetic field, the magnetic field lines are cut and current is produced because the magnetic lines of force are applying a force on the free electrons in the conductor and causing them to move. So the answers will be:

(i) no change
(ii) no change
(iii) no change
(iv) pointer flickers between A and B
