Approximately 41,000 years ago, Earth’s magnetic field briefly reversed during what is known as the Laschamp event. During this time, Earth’s magnetic field weakened significantly—dropping to a minimum of 5% of its current strength—which allowed more cosmic rays to reach Earth’s atmosphere. […]
Despite being essential to life on Earth, the magnetic field isn’t something we can actually see in itself, or 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 that protects us, the result is pretty scary. […]
Supporting a Danish university research project in sustainable cooling, Bakker Magnetics has helped fabricate a magnetocaloric heat pump that involves one of the most complex magnetic systems it has ever built. Shown above are the […]
