Earth’s frightening sound: for the first time the “metallic background” of the magnetic field

A little scary, metallic and frightening is the sound of the protector magnetic field to her a land I first heard.

According to the European Space Agency (ESA), scientists at the Technical University of Denmark have taken magnetic signals recorded by European Swarm satellites and converted them into sounds.

In fact, the same magnetic field around our planet cannot be seen or heard directly. It is a complex and dynamic “bubble”. It keeps us safe From cosmic radiation and charged particles from the powerful solar “wind”. When these particles collide with atoms and molecules — primarily oxygen and nitrogen — in Earth’s upper atmosphere, some of the collisions turn into stunning blue-green aurora.

The Earth’s magnetic field is mainly caused by an extremely hot and permanent “ocean”. of molten iron in the outer core of our planet, creating electric currentswhich in turn generates the electromagnetic field.

The satellites of the European Space Agency’s triple Swarm mission, launched in 2013, study Earth’s magnetic field through careful satellite recording. Signals From. Danish researchers and musicians have used this magnetic data, both from the Earth’s core and from a geomagnetic storm created after a solar flare, to convert it into sounds, which sound like… Nightmare wallpaper.

As they mentioned, their intention is not to frighten people, but to remind them of the existence of the magnetic field, and although it sounds a bit alarming, it’s actually life on Earth depend on it.

A series of loudspeakers at Solbjerk Square in Copenhagen will broadcast the sound of the magnetic field periodically throughout the week of October 24-30.
