From India Today Web Desk: The magnetic field, the complex and dynamic bubble that protects the Earth from cosmic radiation and charged particles carried by strong winds blowing from the sun, is invisible. However, for the first time, scientists have revealed what it looks like.
Scientists at the Technical University of Denmark have converted a magnetic signal into sound and it looks scary. The magnetic field is largely generated by the swirling and extremely hot sea of molten iron that forms the outer core about 3,000 kilometers below our feet.
When they form beneath the planet, their effects appear 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 and blue light seen as the Northern Lights.
The European Space Agency is trying to unravel the secrets of the Earth’s magnetic field using the three Swarm satellites launched in 2013. Scientists are trying to better understand how the magnetic field is created by accurately measuring magnetic signals not only from the Earth’s core. But also from the mantle, crust and oceans, as well as the ionosphere and magnetosphere.

The team used data from the European Space Agency’s Swarm satellite, as well as other sources, and used these magnetic signals to manipulate and control the sound representation of the underlying field. This project is definitely a useful exercise in bringing art and science together, ”explains musician and project supporter Klaus Nielsen from the Technical University of Denmark.
The European Space Agency (ESA) says the idea is to alert everyone to the existence of a magnetic field, and that although the rumbling is a bit worrying, the existence of life on Earth depends on it.
“We were able to produce a very attractive sound system consisting of more than 30 field-installed speakers at Solbjerg Square in Copenhagen. We set it up so that each speaker represents a different location on Earth and shows how our magnetic field has fluctuated over the past 100,000 years, “added Klaus Nielsen.
