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 ...

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 ...

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 ...

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 ...

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

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 ...

Are you ready to find a new direction? This experiment uses household items to make a useful tool. Follow along with ABC11 Science Club with BASF and discover how to make a compass at home! Adult ...

Bizarre magnetic behavior that was predicted by a famous physicist more than 80 years ago has finally been demonstrated in the lab, according to a new study. The behavior of an electron in response to ...
