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 ...

Modern steel ships warp a magnetic compass with both permanent and induced magnetism, and the binnacle is packed with clever countermeasures to cancel it out. This breaks down hard iron vs soft iron ...

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 ...
