This means that their magnetism is there all the time and cannot be turned on or off as it can with an electromagnet. Converting a magnet to a non-magnet is called demagnetisation. Magnets are ...

A trio of physicists, two with Coventry University, in the U.K., and the third with Laboratoire National des Champs ...

Since ancient times, the sun has been known as a giver of light and heat, a source of life. Plants are coaxed from the Earth ...

Eurasian reed warblers don’t just get a sense of direction from Earth’s magnetic field – they can also calculate their ...

Iron particles effectively act as tiny magnets that can record both magnetic field strength and direction when the process of crystallization locks them in place. The researchers found that rocks ...

In a paper published in the journal Nature Physics, researchers used a superconducting quantum simulator to emulate charged ...

The new magnet is capable of creating a magnetic field of 42.02 tesla, which is more than 800,000 times stronger than the Earth’s and beats the 41.4 tesla record set by the US National Magnetic ...

Studies into whether "static" magnetic therapy alleviates pain have failed to produce convincing evidence the treatments are ...

Study finds that demagnetized Martian basins may indicate a reversing dynamo, not early cessation, impacting our ...

An application note from an IEEE Magazine shows that STT-MRAM memories should be able to achieve high densities with simple precautions in normal ambient magnetic fields.

Mars' global magnetic field may have hung around for 200 million years longer than scientists had thought, possibly giving ...

Researchers uncover how Martian magnetic fields are impacted by dynamo reversals through new models of basin cooling and magnetisation.
