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

Magnetic compasses can be fooled by steel hulls and shifting magnetic poles, so ships turn to gyroscopes instead. This video breaks down how gyrocompasses use Earth’s rotation to find true north, and ...

The magnetized needle of a conventional compass wants to align with Earth’s magnetic field—helpful, unless you’re near the poles, where the field tugs straight downward, rendering magnetic compasses ...

At some point during our primary school careers, most of us probably constructed a simple compass, often by floating a ...
