How does a magnetic compass work? Well, it’s all down to basic physics and human ingenuity. The key component of a standard baseplate compass is its magnetized needle, which is allowed to spin freely ...

For the first time, researchers measured the magnetic pull inside a single bacterium, turning a biological mystery into hard ...

Some bacterial species possess an astonishing ability: They use Earth's magnetic field to orient themselves. To better ...

Some inventions are so simple that it’s hard to improve them. The magnetic compass is a great example — a magnetized needle, a bit of cork, and a bowl of water are all you need to start navigating the ...

A built-in "compass" made of magnetic nanoparticles helps them to reliably find the optimal habitat. Researchers at the University of Basel have now unlocked the magnetic properties of individual ...

From ancient compasses to modern smartphones, magnetometers have quietly shaped how we sense and navigate the world. Let us explore the fundamentals behind these field-detecting devices. Magnetic ...
