Magnetic Inclination Formula:
| From: | To: |
Magnetic inclination, also known as magnetic dip, is the angle made by the Earth's magnetic field lines with the horizontal. It is a crucial parameter in geomagnetism and navigation, indicating how steeply the magnetic field dips into the Earth.
The calculator uses the magnetic inclination formula:
Where:
Explanation: The formula calculates the angle whose tangent is the ratio of the vertical component to the horizontal component of the magnetic field.
Details: Magnetic inclination is essential for understanding Earth's magnetic field, navigation systems, and studying geomagnetic phenomena. It helps in calibrating compasses and other magnetic instruments.
Tips: Enter the vertical and horizontal components of the magnetic field in nanoteslas (nT). Both values must be positive and non-zero for accurate calculation.
Q1: What is magnetic inclination used for?
A: Magnetic inclination is used in navigation, geophysics, and studying Earth's magnetic field. It helps determine the dip angle of magnetic field lines.
Q2: How is magnetic inclination measured?
A: It is measured using instruments like dip circles or calculated from the vertical and horizontal components of the magnetic field.
Q3: What are typical values of magnetic inclination?
A: Magnetic inclination varies with location. At the magnetic equator, it is 0 degrees, and at the magnetic poles, it is 90 degrees.
Q4: Why is magnetic inclination important for glasses?
A: For glasses with magnetic components, understanding magnetic inclination can help in designing and calibrating magnetic attachments or features.
Q5: Can magnetic inclination change over time?
A: Yes, magnetic inclination can change due to variations in Earth's magnetic field, known as secular variation.
