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 ...

Compasses were the trusted companions of sailors, explorers, and travelers for centuries, offering a simple way to find north. A small magnetized needle is set on a tiny pivot, allowing it to move and ...

On Earth, we have an incredibly useful of navigating our way around: a magnetized needle (suspended in a liquid or inside a compass) will align itself with our planet's magnetic field, and point you ...

A new model uncovers how Earth’s liquid core has sustained its magnetic field since the planet’s beginnings, offering new ...

Dan Joling of Anchorage was set to photograph the full moon rising over the Port of Anchorage on Jan. 6. His research told him the moon would pop over the horizon at a certain number of degrees from ...
