European Space Agency: The magnetic field is a complex and dynamic bubble that shields the Earth from cosmic rays. Because of this magnetic field, strongly charged airborne particles from the Sun cannot reach the Earth. But what is that magnetic field sound, have you ever heard it before? Scientists have revealed for the first time what the Earth’s magnetic field sounds like. Scientists at the Technical University of Denmark converted magnetic signals into sound. That word is really scary! The magnetic field is mainly generated by a sea of superheated, swirling liquid iron that forms the outer core 3,000 kilometers below our feet.
Although it originates below the planet, its effects can also be seen in the atmosphere above us. When charged particles from the Sun collide with atoms and molecules, mainly oxygen and nitrogen, in the upper atmosphere, some of the energy from the collision is converted into green-blue light, which is seen as the aurora borealis.
With the help of the Swarm satellites launched by the European Space Agency in 2013, scientists are trying to unravel the mysteries of Earth’s magnetic field. They seek to better understand how the magnetic field is generated by accurately measuring magnetic signals not only from the Earth’s core, but also from the mantle, crust, oceans, ionosphere, and magnetosphere.
“The team used data from ESA’s Swarm satellite and other sources, and used these magnetic signals to manipulate and control the sonic representation of the core field,” says Klas Nielsen, a musician and project supporter at the Technical University of Denmark. This project is indeed an effective one in bringing art and science together.
Meanwhile, the European Space Agency (ESA) said the concept reminds everyone that magnetic fields exist. Although its roar is somewhat unpleasant, life on Earth depends on it.
“We had access to a very impressive sound system consisting of over 30 loudspeakers dug into the ground at Solbjörg Square in Copenhagen. “We set it up so that each speaker represents a different place on Earth and shows how our magnetic field has fluctuated over the past 100,000 years,” Klaas Nielsen added.
