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 ...

There are organisms that can use the magnetic field of the earth to navigate, including animals like honey bees and migratory birds, and some bacteria. Scientists have now learned more about how a ...

If shrunken down to micron size, a compass needle could wobble. (Courtesy: iStockphoto/tobias machhaus) A tiny magnetic needle just 10 μm long could be used to create a magnetic-field sensor that – if ...

At some point during our primary school careers, most of us probably constructed a simple compass, often by floating a magnetized needle on a cork in a cup of water. The water in such a configuration ...

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 ...

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 ...

HONOLULU (HawaiiNewsNow)- Dr.V and Taizo Braden are back at the Honolulu Theater for Youth. Let's see how a compass works and how you can make one. Fill your glass bowl with water. Run the magnet over ...

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 ...
