magnetic field

Until now, however, they've focused primarily on detecting gamma rays from these axions' slow transformation into photons in the magnetic fields of galaxies.

The risk was thought to increase toward the poles, where Earth’s magnetic field funnels solar storms.

"The combination of experimental results and theoretical insights provides a comprehensive picture of how magnetic fields can enhance catalytic performance," added Li, "This can serve as guidance when designing new catalysts in the future."

A planet’s magnetic field traps any gases and other material coming off the planet and its moons.

The first colonists would encounter a barren landscape without water or breathable atmosphere, bathed in deadly solar and galactic radiation from which Earthbound humans are protected by our planet’s atmosphere and magnetic field.
