Although essential to life on Earth, the magnetic field is not something that we can actually see by itself, nor ever hear. 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 to keep us safe, the …
