A long-standing mystery in spintronics has just been shaken up. A strange electrical effect called unusual magnetoresistance ...

Issues including resolution, portability and deployment need to be addressed for low-field MRI to be effective in underserved ...

Magnetism on the moon has always been a bit confusing. Remote sensing probes have noted there is some magnetic signature, but far from the strong cocoon that surrounds Earth itself. Previous attempts ...

Geologists have mapped a strange magnetic anomaly in Australia – and in a stunning coincidence, it happens to look remarkably like the continent it lurks beneath. The anomaly seems to feature its own ...

A single, ultrafast laser pulse has flipped the polarity of a ferromagnet without first heating it to the brink of losing its ...

Small screws disappear on the floor faster than you can blink–and the annoying search begins. However, there’s a simple trick that makes life easier for many DIY enthusiasts: A magnetic screwdriver ...

Earth's magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature. Every so often, the magnetic north and south poles swap places in what are ...

The recent Australia Magnetic Anomaly mapping was done using regional aeromagnetic data gathered during the Northern Territory Government’s Bonney Well Survey.

Pacific Fusion today reported results from a series of experiments conducted at Sandia National Laboratories' Z Pulsed Power Facility under a Cooperative Research and Development Agreement. In a ...

Deep beneath the ocean floor, ancient sediments hint that Earth’s magnetic field sometimes changed far more slowly than expected.

Earth’s magnetic field is often described as a steady shield, but the geological record tells a more restless story. Polarity flips, when magnetic north and south swap places, happen several times per ...
