At a place, if the earths horizontal and vertical components of magnet...
Explanation:

Earth's Magnetic Field Components:
- The Earth's magnetic field has both horizontal and vertical components. The horizontal component points towards the magnetic north pole, while the vertical component points downwards towards the Earth's center.

Angle of Dip:
- The angle of dip, also known as the inclination, is the angle at which the total magnetic field lines intersect the Earth's surface. It is the angle between the Earth's magnetic field lines and the horizontal plane.

Equal Horizontal and Vertical Components:
- When the horizontal and vertical components of the Earth's magnetic field are equal, it means that the total magnetic field is equally split between the horizontal and vertical directions.

Angle of Dip Calculation:
- The angle of dip can be calculated using the formula:
Tan δ = Bv / Bh
where δ is the angle of dip, Bv is the vertical component, and Bh is the horizontal component.

Equal Components Result:
- When Bh = Bv, the tangent of the angle of dip becomes 1, which means the angle of dip is 45°.
Therefore, if at a place the Earth's horizontal and vertical components of magnetic fields are equal, the angle of dip will be 45°.
