The angle which the total magnetic field of earth makes with the surface of the called

Answer

To solve the question regarding the angle which the total magnetic field of the Earth makes with the surface of the Earth, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Earth's Magnetic Field**:
The Earth has a magnetic field that can be represented as a vector. This vector can be broken down into two components: a horizontal component and a vertical component.

2. **Defining the Components**:
- The **horizontal component** of the magnetic field is parallel to the surface of the Earth.
- The **vertical component** of the magnetic field points towards the center of the Earth.

3. **Visualizing the Angle**:
When we visualize the magnetic field vector, it makes an angle with the horizontal surface of the Earth. This angle is formed between the horizontal component and the total magnetic field vector.

4. **Naming the Angle**:
The angle that the total magnetic field makes with the horizontal surface of the Earth is known as the **angle of inclination** or **angle of dip**.

5. **Conclusion**:
Therefore, the angle which the total magnetic field of the Earth makes with the surface of the Earth is called the **angle of inclination** or **angle of dip**.

### Final Answer:
The angle which the total magnetic field of the Earth makes with the surface of the Earth is called the **angle of inclination** or **angle of dip**.
