A weird dead star may have a solid-like surface made of iron crystals
3 November 2022
X-ray observations show that a distant magnetar may have a surface made of a strange material somewhere between a solid and a fluid instead of a gaseous one like most stars
Computer made from swirly magnets can recognise handwritten digits
30 September 2022
A prototype computer built using a magnetic material called a skyrmion has been programmed to recognise handwritten digits. The approach could be particularly energy-efficient
Tiny magnetic waves have been discovered in Earth’s core
21 March 2022
Fluctuations in Earth’s magnetic field that repeat every seven years can be used to probe the inner workings of our planet
Tsunamis create magnetic fields that could act as early warning system
24 December 2021
The movement of seawater in a tsunami generates a magnetic field that travels ahead of changes in sea level, which could help us predict and prepare for it
iPhone and Apple Watch magnets are strong enough to disrupt pacemakers
26 August 2021
The magnets used in the iPhone 12 and Apple Watch 6 are strong enough to disrupt medical implants such as pacemakers if held too close to the body, according to tests done by the US Food and Drug Administration
Handheld railgun as powerful as an air rifle to go on sale in the US
12 August 2021
An electromagnetic rifle, a device that uses electromagnetic coils to push a steel projectile down its barrel, is now being offered for pre-order in the US
Black holes with magnetic field ‘hair’ shed it in loops of hot plasma
2 August 2021
When black holes are born with magnetic fields, simulations show they shed those fields quickly, in accordance with the predictions of the no-hair theorem
Best ever views of Mars's weird auroras taken by UAE's Hope orbiter
30 June 2021
The United Arab Emirates’ Hope orbiter has taken the most detailed images ever of Mars’s strange, patchy auroras, which could help explain how the planet’s air disappeared
We may finally know how migrating birds sense Earth's magnetic field
23 June 2021
A molecule in the eyes of migrating birds called cryptochrome 4 is sensitive to magnetism, potentially giving the animals an internal compass
