B

Step 1: Understand the scenario. We have a horizontal conductor oriented in a north-south direction, falling under the influence of gravity.
Step 2: Apply Faraday's Law of Electromagnetic Induction. It states that a change in magnetic flux through a circuit induces an electromotive force (e.m.f.) in the circuit. The conductor is falling, thus cutting through the Earth's magnetic field lines.
Step 3: Determine the orientation of Earth’s magnetic field. In the northern hemisphere, the magnetic field lines point downwards into the ground, and they are directed towards the north.
Step 4: Analyze the motion of the conductor. As the conductor falls, it moves through the magnetic field lines. According to the right-hand rule, when the conductor moves downward (falling) and the magnetic field points downward (into the Earth), the induced current's direction will be from North to South.
Conclusion: Therefore, the correct answer is that a current will be induced from North to South.
Therefore, the answer is B.
