💡 The angle of dip is positive in the Northern Hemisphere (pointing down) and negative in the Southern Hemisphere (pointing up).
The (or magnetic inclination) is the angle that the Earth's total magnetic field intensity makes with the horizontal surface at a specific location. Licensed by Google Core Components The Earth's magnetic field ( ) can be resolved into two rectangular components: Horizontal Component ( BHcap B sub cap H ): The part of the field parallel to the Earth's surface. Vertical Component ( BVcap B sub cap V ): The part of the field perpendicular to the surface. Mathematical Formulas The relationship between the total field ( ), the components, and the angle of dip ( ) is given by: angle of dip
