See a new map of the universe’s magnetic fields – the largest and most detailed ever made
Magnetic fields are a fundamental part of the universe. They govern how small particles – the building blocks of planets, ...
TMS is a noninvasive treatment that uses magnetic fields to stimulate nerve cells in the brain. “As its name implies, it is actually working on the brain transcranially, meaning through the skull,” ...
Our planet’s magnetosphere has seen dramatic shifts across its history—even total reversals—but this recent wrinkle doesn’t pose a threat to life Earth’s magnetic field surrounds the planet, with ...
Earth’s magnetic field feels permanent, but science tells a far more fragile story. Long before modern life emerged, the invisible shield protecting the planet from solar radiation weakened to a ...
Magnetic force microscopy (MFM) is one of the modes of scanning probe microscopy (SPM). As the name implies, it is used to map magnetic characteristics. MFM investigates the local magnetic fields at ...
