WMM (World Magnetic Model):
Download ERSI shapefiles from: https://data.ngdc.noaa.gov/geomag/wmm/wmm2025/shapefiles/
Open D_2025.shp in QGIS: https://qgis.org/

QGIS geojson export doesn't support styles (See: https://github.com/qgis/QGIS/issues/21195) so manually edit the geojson and insert:
"stroke": "#ff0000" properties to set color. Negative blue, positive red, 0 green.
"stroke-width": 0.5, for contours that aren't multiples of 10 and 1.0 for those that are.
