Of course, there's Earth's magnetic field, which deflects dangerous cosmic radiation, wiggles our compasses, and guides flocks of migrating birds. But other planets and stars have magnetic fields ...

where the atmosphere and planetary magnetic field provide a shield from space radiation, astronauts are exposed to ...

Our planet’s magnetic field helps protect us from radiation, solar winds, and extreme temperature changes. The study found that the Earth’s magnetic field experienced a phase of drastic ...

A flower-shaped structure only a few micrometers in size made of a nickel-iron alloy can concentrate and locally enhance ...

The Magnetic Field Safety Program is managed by the Radiation Safety office; a subset of the Office of Environmental and Emergency Management (EEM). We are here to ensure that Magnetic Fields on ...

Scientists have unlocked a way to read magnetic orientation at record-breaking speeds using terahertz radiation. Modern hard ...

If the Earth's field is disrupted, it may cause problems in technology and navigation, as well as expose the planet to unwanted radiation. Magnetic poles move because the "liquid metal in the ...

"We now can determine the magnetic orientation of a material much quicker with light-induced current pulses," explains Dr. Jan-Christoph Deinert of HZDR's Institute of Radiation Physics.

“Our natural magnetic fields offer a different perspective ... but many of them involve radiation or contrast dyes, or invasive procedures,” says Cai. “Our device offers an alternative ...
