The angle of dip at the magnetic pole is

Options

A. zero
B. `90^(@)`
C. `45^(@)`
D. `180^(@)`

Answer

To find the angle of dip at the magnetic pole, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Concept of Angle of Dip**:
- The angle of dip (or magnetic dip) is the angle made by the Earth's magnetic field lines with the horizontal plane. At different locations on Earth, this angle varies.

2. **Identifying the Magnetic Poles**:
- There are two magnetic poles: the North Magnetic Pole and the South Magnetic Pole. The angle of dip is different at these two locations.

3. **Analyzing the Angle of Dip at the North Magnetic Pole**:
- At the North Magnetic Pole, the magnetic field lines point vertically downwards. Therefore, the angle of dip at the North Magnetic Pole is 90 degrees.

4. **Analyzing the Angle of Dip at the South Magnetic Pole**:
- Conversely, at the South Magnetic Pole, the magnetic field lines point vertically upwards. Hence, the angle of dip at the South Magnetic Pole is 270 degrees (or -90 degrees, depending on the convention used).

5. **Conclusion**:
- The angle of dip at the magnetic pole can be summarized as follows:
- North Magnetic Pole: 90 degrees
- South Magnetic Pole: 270 degrees

6. **Final Answer**:
- The angle of dip at the magnetic pole is 90 degrees at the North Magnetic Pole.
