The correct Answer is:
To determine where the neutral point lies when a magnet is placed with its North pole pointing North, we can follow these steps: ### Step 1: Understand the Concept of Neutral Point The neutral point is the location where the magnetic field due to the magnet is zero. This occurs when the magnetic field from the magnet cancels out the Earth's magnetic field. **Hint:** Recall that the Earth's magnetic field has both a North and South component, and the neutral point is where these fields balance each other out. ### Step 2: Identify the Position of the Magnet When the North pole of the magnet is aligned with the geographical North, it means that the North pole of the magnet is pointing towards the Earth's North pole. **Hint:** Visualize the orientation of the magnet in relation to the Earth's magnetic field. ### Step 3: Determine the Location of the Neutral Point For a magnet, the neutral point lies on the equatorial line when the North pole is pointing towards the geographical North. The equatorial line is the line that runs perpendicular to the axis of the magnet and is located in the plane that bisects the magnet. **Hint:** Remember that the equatorial line is different from the axial line, which runs along the length of the magnet. ### Step 4: Conclusion Since the North pole of the magnet is pointing North, the neutral point will be located on the equatorial line of the magnet. **Final Answer:** The neutral point lies on the equatorial line of the magnet. ### Summary of Steps: 1. Understand the neutral point concept. 2. Identify the orientation of the magnet. 3. Determine that the neutral point is on the equatorial line. 4. Conclude that the neutral point lies on the equatorial line of the magnet.
