” We got to a really intriguing sound system including over 30 loudspeakers went into the ground at the Solbjerg Square in Copenhagen.
” We have actually set it up so that each speaker represents a various area in the world and demonstrates how our magnetic field has actually fluctuated over the last 100,000 years.
” Throughout today, visitors will have the ability to hear the amazing rumble of our magnetic field– so if you are in Copenhagen occur and have a look at this unique chance.
” The rumbling of Earths electromagnetic field is accompanied by a representation of a geomagnetic storm that arised from a solar flare on November 3, 2011, and indeed it sounds pretty scary.”

The objective, obviously, is not to terrify individuals– it is a wacky way of advising us that the electromagnetic field exists and although its rumble is a little unnerving, the existence of life in the world depends on it.
The loudspeakers at Solbjerg Square in Copenhagen, Denmark, will broadcast the rumble of Earths magnetic field bbetween October 24– 30 at around 8 a.m, 1 p.m., and 7 p.m.
Regardless of being important to life on Earth, the magnetic field isnt something we can really see in itself, or ever hear. Extremely, scientists at the Technical University of Denmark have taken magnetic signals measured by ESAs Swarm satellite objective and transformed them into noise– and for something that protects us, the result is pretty frightening.

Earth is surrounded by a system of electromagnetic fields, called the magnetosphere, which is essential to life in the world. The magnetic field isnt something we can actually see in itself, or ever hear. Remarkably, scientists at the Technical University of Denmark have actually taken magnetic signals determined by ESAs Swarm satellite objective and converted them into sound. For something that protects us, the outcome is quite frightening.
Earths magnetic field is a complex and dynamic bubble that keeps us safe from damaging cosmic radiation and charged particles carried by powerful solar winds flowing from the Sun. When these particles hit particles and atoms– primarily oxygen and nitrogen– in the upper atmosphere, a few of the energy in the accidents is changed into the green-blue light that is common of the aurora borealis. These “northern lights” can often be seen from high-northern latitudes.
The magnetic field and electric currents in and around Earth create intricate forces that have an immeasurable impact on daily life. The field can be believed of as a big bubble, safeguarding us from cosmic radiation and charged particles that bombard Earth in solar winds. Credit: ESA/ATG medialab
The aurora borealis provides a visual display screen of charged particles from the Sun interacting with Earths magnetic field, it is another matter altogether to really be able to hear the magnetic field produced by Earth or its interaction with solar winds.
Our magnetic field is mostly produced by an ocean of superheated, swirling liquid iron that makes up the external core around 3,000 km (1,900 miles) beneath our feet. Acting as a spinning conductor in a bike dynamo, it develops electrical currents, which in turn, produce our continuously changing electro-magnetic field.
ESAs trio of Swarm satellites, which were released in 2013, are being used to comprehend exactly how our electromagnetic field is generated by exactly measuring the magnetic signals that stem not only from Earths core, however also from the mantle, crust, and oceans, along with from the ionosphere and magnetosphere. Swarm is likewise resulting in new insights into the weather condition in space.

Klaus Nielsen, an artist and task fan from the Technical University of Denmark, discusses, “The group used information from ESAs Swarm satellites, along with other sources, and used these magnetic signals to control and control a sonic representation of the core field. The job has actually definitely been a fulfilling exercise in bringing art and science together.”
It may sound like the things of headaches, but, remarkably, this audio clip represents the electromagnetic field created by Earths core and its interaction with a solar storm.
Regardless of being vital to life on Earth, the magnetic field isnt something we can actually see in itself, or ever hear. Earth is surrounded by a system of magnetic fields, called the magnetosphere, which is important to life on Earth. The magnetic field isnt something we can in fact see in itself, or ever hear. Earths magnetic field is a complex and vibrant bubble that keeps us safe from hazardous cosmic radiation and charged particles carried by powerful solar winds flowing from the Sun. The magnetic field and electrical currents in and around Earth generate complicated forces that have an immeasurable effect on everyday life.
