Scientists convert data from the Earth’s magnetic field into sound; listen | space

Although essential to planet Earth, Earth’s magnetic field It is not something that can be seen or heard. But by collecting data from the three Swarm mission satellites, European Space Agency (ESA)Scientists from the Technical University of Denmark were able to convert information about this force into sounds.

Accuracy data magnetic signals They were captured by instruments derived from the ionosphere, magnetosphere, core, mantle, crust and Earth’s oceans.

The team used data from the European Space Agency’s Swarm satellites, as well as other sources, and used these magnetic signals to manipulate and control the acoustic representation of the central field. The project was certainly a useful exercise in bringing art and science together,” comments musician and project supporter Klaus Nielsen, from the Technical University of Denmark, In a press release.

How do you check In the video belowthe sound generated from our data magnetic field It’s not the most fun. That’s because the boom is caused by a geomagnetic storm caused by a solar flare On November 3, 2011. In the video, audio was played at a demonstration at Solbjerg Square in Copenhagen, the Danish capital.

In addition to recreating the sound of the magnetic field with a solar activityThe researchers were able to create an audio system with more than 30 speakers arranged on the arena floor. “We set it up so that each speaker represents a different location on Earth and shows how our magnetic field has fluctuated over the past 100,000 years,” Nielsen explains.

Earth’s magnetic field is created by an ocean liquid iron Extremely hot and whirling, it lies 3,000 kilometers below our feet. This metallic sphere acts as a conductor and generator of electric currents, which in turn constantly generate the magnetic field.

Another way to describe it is that the field looks like a complex and dynamic bubble protecting us from it cosmic radiation and solar particles carried by strong winds.
