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:
📍 The magnetic field is purely vertical. The angle of dip is 90∘90 raised to the composed with power Measurement Tools
💡 The angle of dip is positive in the Northern Hemisphere (pointing down) and negative in the Southern Hemisphere (pointing up).
