Although it is essential to life on Earth, the magnetic field is not something we can actually see or hear.
The magnetic grid protects us from the effects of cosmic rays and solar storms.

But that’s a story from the past. Scientists from the Technical University of Denmark used magnetic field signals measured by the European Space Agency’s (ESA) Swarm satellite and converted them into sound.
The result is a pretty scary sound.
The Earth’s magnetic grid is a complex bubbleplays a role in helping protect humans from attacks by cosmic rays, as well as charged particles blown by powerful solar winds.
When charged particles collide with atoms and molecules, mainly oxygen and nitrogen, located in the upper atmosphere, part of the energy formed during the collisions is transformed into green and blue light, a characteristic element of aurora.
Auroras can sometimes be seen in high latitude areas of the Northern Hemisphere.
While auroras give us concrete insight into how charged particles interact with Earth’s magnetic grid, hearing the sound coming from the magnetic grid as it is created by Earth or as it interacts with the solar wind is a any other story.
The Earth’s magnetic grid created by a “ocean“Very hot liquid iron, continually swirling in the outer crust zone of the Earth’s core.
This area is located deep underground, approximately 3,000 km from us. Acts like a continuously rotating electric coil in a bicycle dynamo, “ocean” This hot iron continually creates electrical currents, which create our ever-changing electromagnetic field.

Launched in 2013, the trilogy Satellite swarm from ESA are used to understand how the magnetic grid is created, by measuring magnetic signals from the Earth’s core, mantle, crust and oceans, as well as the ionosphere and magnetosphere.
Swarm also leads to new and deeper insights into space weather.
Musician Klaus Nielsen from the Technical University of Denmark, who also supports the project, explains: “The team collected data from ESA’s Swarm satellites, as well as various other sources. Then we transform these magnetic field signals into sound. The project is certainly a rewarding activity, as it brings art and science together. »
The sound sounds quite scary, with mysterious rumbles, crashes and crashes. But remember that this sound is created from the activity of the earth’s magnetic grid, we will find it very interesting.

“We were approached with a very interesting sound system, consisting of over 30 speakers placed underground at Solbjerg Square in Copenhagen. We set each speaker to represent a different location on Earth and show how our magnetic grid has fluctuated over the past 100,000 years. »said musician Nielsen.
According to this musician, throughout this week, the public will have the opportunity to hear the mysterious rumbling of the magnetic grid.
Therefore, if you are in Copenhagen, you should not miss this unique experience opportunity.
The scientists behind the project also added that their goal was not to scare people.
It’s actually a way of reminding us of the existence of the magnetic grid, and although it sounds scary, life on Earth depends on it.
