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 ...

Earth is surrounded by a magnetic field generated by electric currents from within the planet. Compasses take advantage of this field to identify north and serve as a navigational aid. But one social ...

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

Earth’s magnetic field isn’t just a compass trick it’s a shield that protects life and technology from harmful radiation. See how magnetic shifts, excursions, and anomalies impact satellites, power ...

We may finally know the secret to how migrating birds can sense Earth’s magnetic fields: a molecule in their eyes called cryptochrome 4 that is sensitive to magnetism, potentially giving the animals ...
