Answer:
The direction of the earth's magnetic field is from geographic South to North. Let the direction of current in the conductor be from West to East. Applying Fleming's left-hand rule, we find that the direction of the force acting on the conductor will be vertically upwards.
(a) By reversing the direction of current the direction of force experienced by the conductor will be reversed i. e., it acts vertically downwards. (1)
(b) The magnitude of the force is doubled i.e., . (1)
