Prior to about 3.56 billion years ago, the dynamo effect from these factors combined created a magnetic field, albeit one much weaker than Earth’s present magnetic field (which measures about 50 ...

During a brief but dramatic chapter in Earth's history about 41,000 years ago, the planet’s magnetic field nearly collapsed. What followed was a cascade of environmental and biological changes ...

This innovation opens up new technological options for improving the performance of small magnetic sensors and for developing multifunctional magnetic components. In the future, such microstructures ...

Soon you can take a portable version of the Earth’s magnetic field to outer space It will protect you from deadly radiation exposure. Updated: Mar 12, 2025 08:17 AM EST ...

Earth’s magnetic field is detected by species across the animal kingdom, but new research suggests that sea turtles may be using it in a different way.

The sun’s solar activity reaches its peak at the middle of this cycle. According to NASA, the sun’s excess solar flares and winds wreak havoc on the Earth’s magnetic field.

The maximum field tolerance of these MRAM devices is between a few tens of milliTesla, mT, to 100mT, depending upon the MRAM target application. 10mT in SI units is 100G in CGS units of magnetic ...

A Breakthrough Study Suggests Magnetic Fields Could Manipulate Human Brains Scientists just did it to mice—and we may be next. By Darren Orf Published: Aug 05, 2024 9:32 AM EDT 4 ...

Surgeons have successfully implanted an artificial titanium heart in the chest of a human patient that is powered by the same ‘maglev’ technology used in the creation of high-speed trains.

Scientists theorize that without the protection of the magnetic field roughly 600 million years ago, solar radiation pounded the Earth’s atmosphere, stripping away hydrogen and other light gases ...
