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 ...

The compass—oldest known navigating instrument—has been revolutionized. Last week Bendix Aviation Corp. announced a new automatic compass that makes the old magnetic needle* look as obsolete as a ...

THE subject of this lecture is the gyrostatic compass, often called the gyro-compass. An engineer of my acquaintance was asked if he under-stood what a gyro-compass was, and he replied, “Of course I ...

Here's how to make a magnetic compass that points north using the amazing invisible force of magnetism. And there are only a few things that we need:A long large needle, a piece of cork carefully ...

The magnetic compass that birds use for orientation is affected by polarized light. The magnetic compass that birds use for orientation is affected by polarised light. This previously unknown ...

Most people assume a compass will behave perfectly, no matter where you take it, but the magnetic pole is a bit of a troublemaker. The rules you rely on everywhere else on the planet start to wobble ...
