![]() ![]() “The rumbling of Earth’s magnetic field is accompanied by a representation of a geomagnetic storm that resulted from a solar flare on November 3, 2011, and indeed it sounds pretty scary.” “Throughout this week, visitors will be able to hear the amazing rumble of our magnetic field – so if you are in Copenhagen come along and check out this unique opportunity. “We have set it up so that each speaker represents a different location on Earth and demonstrates how our magnetic field has fluctuated over the last 100,000 years. “We gained access to a very interesting sound system consisting of over 30 loudspeakers dug into the ground at the Solbjerg Square in Copenhagen. It might sound like the stuff of nightmares, but, remarkably, this audio clip represents the magnetic field generated by Earth’s core and its interaction with a solar storm. The project has certainly been a rewarding exercise in bringing art and science together.” Klaus Nielsen, a musician and project supporter from the Technical University of Denmark, explains, “The team used data from ESA’s Swarm satellites, as well as other sources, and used these magnetic signals to manipulate and control a sonic representation of the core field. Strength of the magnetic field at Earth’s surface. These “northern lights” can sometimes be seen from high-northern latitudes. When these particles collide with atoms and molecules – mainly oxygen and nitrogen – in the upper atmosphere, some of the energy in the collisions is transformed into the green-blue light that is typical of the aurora borealis. For something that protects us, the result is pretty scary.Įarth’s magnetic field is a complex and dynamic bubble that keeps us safe from harmful cosmic radiation and charged particles carried by powerful solar winds flowing from the Sun. But, remarkably, scientists at the Technical University of Denmark have taken magnetic signals measured by ESA’s Swarm satellite mission and converted them into sound. ![]() However, the magnetic field isn’t something we can actually see in itself, or ever hear. Credit: Ben Rider – Crimson SoundĮarth is surrounded by a system of magnetic fields, called the magnetosphere, which is essential to life on Earth. But, remarkably, scientists at the Technical University of Denmark have taken magnetic signals measured by ESA’s Swarm satellite mission and converted them into sound – and for something that protects us, the result is pretty scary. Despite being essential to life on Earth, the magnetic field isn’t something we can actually see in itself, or ever hear.
