Visualization of magnetic field

About 41,000 years ago, during the Laschamp Geomagnetic Excursion, Earth's magnetic field weakened drastically, dropping to just 5% of its current strength. This means that Earth’s natural magnetic shield, which normally protects us from harmful space radiation, was almost entirely gone. The magnetic field lines (seen as white or blue strands) became twisted and chaotic, showing how disordered the field became during the excursion. Normally, these lines flow smoothly from pole to pole, but during this event, they bent, broke, and tangled. The Earth turns red in the visualization, indicating an extremely weak magnetic field. The red color means the planet was barely protected from solar and cosmic radiation. This visualization was created by scientists from DTU and GFZ using data from ESA’s Swarm mission. It includes a stereo soundscape and a visual tracing of the magnetic field lines. This event caused abrupt climate change and mass extinction, and the same thing is happening today!

Real sound of Earth’s magnetic field from space. Magnetic field data collected by Swarm satellites and other sources has been coverted into these frightening sounds (video: a footage from the ISS)

Polarization of light: It is a property of electromagnetic waves. Electromagnetic waves are three dimensional and polarization is a measure of the spatial orientation of electric field and magnetic field vectors.

A bar magnet has a magnetic field around it. The magnetic field around a bar magnet flows from the north pole to the south pole and is strongest at the poles. ✍️
