Visualizing Earth’s magnetic field from 1900 to 2020.
The data is extracted from the 12th International Geomagnetic Reference Field (IGRF),
a mathematical model that can predict magnetic inclination up to the year 2020.
A custom algorithm maps the data into spherical isolines and sends the paths to a
mechanical pen plotter.
The 7 prints show the change in magnetism over time, spanning a 120 year period.
