1. What Is Magnetic Inclination?

Magnetic inclination, also known as magnetic dip, is the angle made by the Earth's magnetic field lines with the horizontal plane. It indicates how steeply the magnetic field lines dive into or emerge from the Earth's surface.

2. How Does The Calculator Work?

The calculator uses the magnetic inclination formula:

Where:

• \( I \) — Magnetic inclination angle (degrees)
• \( Z \) — Vertical component of magnetic field (nT)
• \( H \) — Horizontal component of magnetic field (nT)

Explanation: The formula calculates the angle whose tangent is the ratio of the vertical component to the horizontal component of the magnetic field.

3. Importance Of Magnetic Inclination

Details: Magnetic inclination is crucial for navigation, geophysical studies, and understanding Earth's magnetic field variations. It helps in determining magnetic declination and total field intensity.

4. Using The Calculator

Tips: Enter both vertical and horizontal components in nanoteslas (nT). Values must be positive and non-zero for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is the range of magnetic inclination values?
A: Magnetic inclination ranges from 0° at the magnetic equator to 90° at the magnetic poles.

Q2: How does magnetic inclination vary with location?
A: Inclination increases from the equator towards the poles, providing information about latitude in magnetic navigation.

Q3: What units are used for magnetic components?
A: Magnetic field components are typically measured in nanoteslas (nT) or sometimes in gammas (1 gamma = 1 nT).

Q4: Can inclination be negative?
A: In the northern hemisphere, inclination is positive (downward), while in the southern hemisphere it's negative (upward).

Q5: How is magnetic inclination measured in practice?
A: Specialized instruments called dip circles or inclinometers are used to measure magnetic inclination directly in the field.
