Scientific Principles Behind the Calculator
The Magnetic Declination Calculator is grounded in geomagnetic field principles, as outlined in texts like *Geomagnetism* by Chapman and Bartels and *Introduction to Geomagnetic Fields* by Campbell. Magnetic declination is calculated using a simplified model based on the International Geomagnetic Reference Field (IGRF), which accounts for spatial and temporal variations in the Earth’s magnetic field. The simplified formula used here is:
- Declination (D): D = D₀ + ΔD/Δt × (year - year₀), where D₀ is a baseline declination, ΔD/Δt is the annual change rate, and year₀ is a reference year.
For simplicity, this calculator uses an approximate model with baseline values adjusted by latitude, longitude, and time, acknowledging that real-world applications may require IGRF data for precision. The tool includes input validation to ensure usability and reliability.
