1. What is the Angle of Dip?

Definition: The angle of dip (δ) is the angle made by the Earth's magnetic field with the horizontal plane at any location.

Purpose: It's a fundamental measurement in geomagnetism, helping scientists and navigators understand the Earth's magnetic field orientation.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ \tan(\delta) = \frac{B_H}{B_V} \]

Where:

\( \delta \) — Angle of dip (degrees)
\( B_H \) — Horizontal component of Earth's magnetic field (Tesla)
\( B_V \) — Vertical component of Earth's magnetic field (Tesla)

Explanation: The tangent of the angle of dip equals the ratio of the horizontal magnetic field component to the vertical component.

3. Importance of Angle of Dip

Details: Understanding the angle of dip is crucial for compass navigation, geophysical surveys, and studying Earth's magnetic field variations.

4. Using the Calculator

Tips: Enter both magnetic field components in Tesla. The calculator will compute the angle of dip in degrees.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical angle of dip value?
A: At the magnetic equator it's 0° (horizontal field), increasing to 90° (vertical field) at the magnetic poles.

Q2: How do I measure B_H and B_V?
A: These are typically measured with specialized magnetometers that can detect field components.

Q3: Why is the angle of dip important in navigation?
A: It affects how compass needles align and is crucial for accurate magnetic navigation, especially at high latitudes.

Q4: Does the angle of dip change over time?
A: Yes, it changes gradually due to secular variation in Earth's magnetic field (typically 0.1° per year).

Q5: What's the relationship between total field and components?
A: The total field \( B = \sqrt{B_H^2 + B_V^2} \), combining both components vectorially.
