To solve the problem, we need to find the magnetic moment (M) of the bar magnet given the distance to the neutral point and the magnetic field strength (H) at that point.
### Step-by-Step Solution:
1. **Understanding the Problem**:
- We have a short bar magnet placed with its north pole pointing north.
- The neutral point is located 10 cm away from the center of the magnet.
- The magnetic field strength (H) at this point is given as 0.4 G (Gauss).
