What is the horizontal component of Earth's magnetic field? If the horizontal and vertical components of Earth's magnetic field are equal then what is the angle of dip?

Explanation

To solve the problem, we need to find the horizontal component of Earth's magnetic field and determine the angle of dip when the horizontal and vertical components are equal.

### Step-by-Step Solution:

1. **Understanding Components of Earth's Magnetic Field**:
- The Earth's magnetic field can be resolved into two components: the horizontal component (Bh) and the vertical component (Bv).
- The horizontal component (Bh) is the part of the magnetic field that runs parallel to the Earth's surface, while the vertical component (Bv) runs perpendicular to the surface.
