Name three elements of the earth.s magnetic field which help in defining earth.s magnetic field completely.

Explanation

To define Earth's magnetic field completely, we can identify three key elements:

1. **Angle of Declination**: This is the angle between the geographic plane of the Earth and the magnetic meridian plane. It indicates how much the magnetic north differs from the geographic north.

2. **Angle of Dip**: This is the angle between the total magnetic field and the horizontal line at a given location. It shows how steeply the magnetic field lines are inclined with respect to the Earth's surface.

3. **Horizontal Component of Magnetic Field**: This is the component of the Earth's magnetic field that lies in the horizontal plane. It is essential for understanding the strength and direction of the magnetic field at a specific location.
