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 ...

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

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 ...

When Santa is done delivering presents on Christmas Eve, he must get back home to the North Pole, even if it's snowing so hard that the reindeer can't see the way.

Apple Watch Series 5 is the first version to include a built-in digital compass, but Apple hasn’t managed to change the laws of physics when it comes to how magnets work. For that reason, Apple ...

A ship’s steel hull becomes part of Earth’s magnetic field, which can quietly skew a magnetic compass in different directions as the vessel turns and heels. This explains how binnacle correctors work, ...

The magnetic compass is the last unknown sense in migrating animals. For some scientists, the monarch butterfly is leading ...

A new study found that the larvae of haddock, a commercially important type of cod, have a magnetic compass to find their way at sea. The findings showed that haddock larvae orient toward the ...
