The arms of a deflection magnetometer in tangent B position are placed along the

Options

A. East west direction
B. North south direction
C. North west direction
D. South east direction

Answer

To solve the question regarding the arms of a deflection magnetometer in tangent B position, we will follow these steps:

### Step 1: Understand the Deflection Magnetometer
A deflection magnetometer is an instrument used to measure the magnetic moment and pole strength of a bar magnet. It can also compare the pole strength of two bar magnets.

### Step 2: Identify the Positions of the Magnetometer
The deflection magnetometer has two main positions:
- **Tangent A Position**: In this position, the arms of the magnetometer are aligned in the East-West direction.
- **Tangent B Position**: In this position, the arms are aligned in the North-South direction.

### Step 3: Analyze the Given Information
The question specifies that the arms of the deflection magnetometer are in tangent B position. According to our understanding of the positions:
- In tangent B position, the arms are placed along the North-South direction.

### Step 4: Conclusion
Based on the analysis, since the arms of the deflection magnetometer are in tangent B position, they are indeed placed along the North-South direction.

### Final Answer
The arms of a deflection magnetometer in tangent B position are placed along the North-South direction.
