There are a few ways to do this, but the Halbach array, as [wannabemadsci] explains, allows you to make an array of magnets where one side is very strong, and the other side is very weak.

The universe is soaked in weak-but-persistent magnetic fields. Despite decades of research, astronomers still aren't exactly sure where these magnetic fields came from. But new research suggests they ...

Deep in Chile’s Atacama Desert, scientists studied a green crystal called atacamite—and discovered it can cool itself ...

The research team has identified atacamite as a material with magnetocaloric properties. Natural crystals have long ...

Researchers have developed a new technology that could help measure the invisible forces of magnetism-from inside the human brain to the depths of outer space-without needing bulky shielding or ...

Natural crystals fascinate with their vibrant colors, their nearly flawless appearance and their manifold symmetrical forms.

Type-I multiferroics have a weak magnetoelectric coupling, which means that they fail to effectively couple magnetism and electric fields. On the other hand, Type-II multiferroics exhibit a very ...

The poles of the sun’s magnetic field are fading away. But don’t panic: it’s all part of our host star’s usual 11-year cycle of activity.. Over the past couple of years, solar activity ...

The moon may be silent and still today, but billions of years ago, it likely crackled with magnetic activity. Though the moon now lacks a global magnetic field, its rocks—especially those on the ...

Their starting assumption was that the early Moon had a dynamo that generated a weak magnetic field 50 times weaker than Earth's. The results confirmed that a large asteroid impact, ...

If there had been a gargantuan refrigerator in the early universe, it might have been plastered with little magnetic galaxies. That's because the first direct measurement of an early galaxy's ...
