Ferrofluid—an extraordinary magnetic liquid—reacts in mesmerizing ways when exposed to a powerful magnet. This visual experiment reveals the strange and fascinating behavior of magnetic fields in ...

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 ...

Since they don't, there is little evidence for a strong global magnetic field past that point. The going theory was that, as the planet's core cooled, the entire core became solid, eliminating the ...

Although the magnetic field of Mars hasn’t been in effect for billions of years, the evidence it left behind may suggest that the planet’s core is entirely liquid. Magnetic imprints still exist on ...

For the study, the researchers used computer models based on data obtained from NASA’s now-retired Mars InSight lander to simulate conditions within the interior of Mars depicting the absence of an ...

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 ...

Scientists have discovered a new reason for turtles to dance for joy: Loggerhead sea turtles seem able to discern and remember magnetic field signatures, which could help them find food. The Earth ...

The scientists utilized magnetic fields to control the shape and movements of the shape-shifting liquid metal robots. The hope is that by using magnets to help move and control the shapeshifting ...

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 ...
