Eerie Noise recording from the Earth’s Magnetic Field – ESA European Space Agency

Earth’s magnetic field is an intricate and ever-changing shield that protects us from cosmic rays and particles brought by potent solar winds. These particles, when they collide with atoms and molecules, mainly oxygen and nitrogen, in the Earth’s upper atmosphere, convert some of their energy into the green-blue light often seen in the aurora borealis at higher northern latitudes.

You can listen the clip from the link below.

The aurora borealis is a visible manifestation of the interaction between the Sun’s charged particles and Earth’s magnetic field. However, the prospect of audibly detecting Earth’s magnetic field or its interactions with solar winds is a different concept.

The magnetic field of our planet primarily originates from a vast ocean of intensely hot, swirling liquid iron constituting the outer core, located about 3000 km below the Earth’s surface. This liquid iron functions like the spinning conductor in a bicycle dynamo, producing electrical currents that, in turn, generate our constantly evolving electromagnetic field.
