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 ...

An Egypt Air engineer believes magnetic compass deviation has been overlooked in the search for Malaysia Airlines Flight 370, ...

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 ...

Using a magnetic compass to calculate the current in a wire. Learn how magnetic fields, compass deflection, and basic electromagnetism principles connect in a practical physics experiment. #MagneticFi ...

In the blink of an eye in geological time, Canada has lost one north pole but gained another, a new and different claim to be ...

Magnetic compasses have long been reliable tools for navigation, especially before the advent of satellites and digital GPS. These timeless instruments align with Earth’s magnetic field, guiding ...

A compass made of light promises to be more sensitive than anything in a Boy Scout’s wildest dreams. A light beam shot through a blob of rubidium atoms can directly and reliably measure the size and ...

The magnetic compass that birds use for orientation is affected by polarized light. That is the finding of researchers in Sweden, who studied zebra finches navigating a simple maze and found that the ...

Monarch butterflies have a keen sense of direction, even on cloudy days. This is because they have a magnetic compass to direct their migration in addition to navigating by the position of the sun, ...

Here’s an amazing fact: Adult robins have a magnetic compass in their right eye that allows them to sense the direction of the Earth’s magnetic field, and navigate when all other landmarks are ...
