Function magneticField

magneticField(
    latDeg: number,
    lonDeg: number,
    options?: MagneticFieldOptions,
): MagneticFieldResult
Computes the full magnetic field at a geographic position using the World Magnetic Model 2025 (WMM2025).

Returns declination, inclination, and all field components (X, Y, Z, H, F).
Parameters
- latDeg: number
  Geodetic latitude in decimal degrees (-90 to 90).
- lonDeg: number
  Geodetic longitude in decimal degrees (-180 to 180).
- Optionaloptions: MagneticFieldOptions
  Optional altitude and date.
Returns MagneticFieldResult
Full magnetic field result with all components.
Example
```
import { magnetic } from '@squawk/flight-math';

const result = magnetic.magneticField(40.0, -105.0, {
  date: new Date(Date.UTC(2026, 0, 1)),
});
console.log(result.declinationDeg);
console.log(result.totalIntensityNt);
```
