Fish, birds, reptiles, amphibians, and even a few mammals rely on magnetoreception for navigation. But the exact mechanism ...

The Sun’s magnetic field is invisible to our eyes, but it quietly shapes everything from the shimmering auroras over the ...

Researchers have found that exposing a certain class of particles -- micron-sized beads endowed with a special magnetic sensitivity -- to a rapidly alternating, rotating magnetic field causes them to ...

A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...

You might be scared if you heard Earth’s North Pole and South Pole were about to flip positions. The sun is about to do the same thing, and it’s not a worry for us. The sun is a big magnetic ball of ...

In the supplemental material the experimental setup is shown (see top image), which is designed to make the individual iron-coated polymer particles rotate. The particles are called Janus particles ...

Scientists in South Korea have developed swarms of tiny magnetic robots that work together like ants to achieve Herculean feats, including traversing and picking up objects many times their size. The ...

The quest for the world's strongest magnet faced a surprisingly violent problem: they kept exploding. At least, that was the issue facing a group of scientists at the National High Magnetic Field ...
