The angle between the earth's magnetic and the earth's geographic axis is

Options

A. zero
B. `11.5 ^(@)`
C. `23^(@)`
D. None of the above

Answer

To find the angle between the Earth's magnetic axis and the Earth's geographic (or geometrical) axis, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Definitions**:
- The **geographic axis** of the Earth is an imaginary line that runs from the North Pole to the South Pole, representing the axis of rotation of the Earth.
- The **magnetic axis** is the line that runs from the magnetic North Pole to the magnetic South Pole, which is where the Earth's magnetic field is directed.

2. **Identify the Angle**:
- The angle between these two axes is known as the **magnetic declination** or **magnetic inclination**.

3. **Recall the Known Value**:
- It is a well-known fact in Earth sciences that the angle between the Earth's magnetic axis and the geographic axis is approximately **11.38 degrees**.

4. **Select the Correct Option**:
- Given the options:
- Option A: 0 degrees
- Option B: 11.5 degrees
- Option C: 23 degrees
- Option D: None of the above
- The closest and correct option is **Option B: 11.5 degrees**.

5. **Conclusion**:
- Therefore, the angle between the Earth's magnetic axis and the Earth's geographic axis is approximately **11.5 degrees**.
