NOAA scientists have spent decades tracking how magnetic north wanders, but recent modeling shows a pole moving in ways ...

The geomagnetic field is generated by fluid convection in Earth’s core. How this dynamo works is complicated, and the field that the core produces is not symmetric. This has been something of a ...

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 ...

Picture yourself standing at the Geographic North Pole with a compass in your hand. You'd expect that trusty needle to point straight down, right into the ground. Turns out that's completely wrong.

Check your compass again – Earth’s north magnetic pole is moving toward Siberia. Since at least the early 19th century, Earth’s north magnetic pole has been situated in the Canadian Arctic and slowly ...

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 ...
