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 ...

Compass Diversified Holdings has continued its strategic buying philosophy with the purchase of a century-old Rochester, N.Y., company whose product line includes the manufacture of rare -earth ...

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 ...

The movement of the magnetic North Pole is the result of the Earth having an active core. The inner core, starting about 3,200 miles below your feet, is solid and under such immense pressure that it ...

A magnetometer is a device that measures magnetism: the direction, strength, or relative change of a magnetic field at a ...

A ship’s steel hull becomes part of Earth’s magnetic field, which can quietly skew a magnetic compass in different directions as the vessel turns and heels. This explains how binnacle correctors work, ...

Artist's depiction of a new strategy for measuring the direction of magnetic fields by exposing a cell containing roughly a hundred billion rubidium atoms to a microwave signal. A team of physicists ...
