magnetic fields

This sounds like something out of the 60s. Could sensing ambient magnetic fields change how we see the world? How would we speak if we could see the physiological effects our words had on others? Would abstract art based on human brain…

While we transmit electricity at high voltages (66 kV or above) to reduce the energy loss from long-distance transmission, electricity transmission and distribution (T&D) losses average about 5% of the electricity that is transmitted…

The Carrington Event of 1859 that disrupted telegraph communications globally is both the world’s best known solar flare and continues to hold the record for the largest observed solar flare. But as we become more dependent on satellite…

Black holes, the regions in spacetime where gravity is so strong nothing can escape, have fascinated astronomers since the 18th Century, when they were first proposed.  Recently, astronomers at MIT and elsewhere have watched for the…

Small magnetic fields from the electricity that lights our homes and powers our appliances are present all around us. Now, Penn State scientists have developed a new mechanism capable of harvesting this wasted magnetic field energy and…

Three recent studies provide a new hypothesis for how Earth’s magnetic field was generated and suggest it formed in the molten lower mantle rather than in its core. The studies are part of a paradigm shift in how we understand earth’s…
