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 ...

Nearly every modern cellphone has a built-in compass, or magnetometer, that detects the direction of Earth's magnetic field, providing critical information for navigation. Now a team of researchers ...

Researchers at the University of Colorado Boulder (CU Boulder) have made a significant advance in magnetic field measurement.

A new technique uses quantum sensors to enable precise measurements of magnetic fields in different directions. A new way of measuring atomic-scale magnetic fields with great precision, not only up ...

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 ...

Recently the MagQuest competition on improving the measuring of the Earth’s magnetic field announced that the contestants in the final phase have now moved on to launching their satellites within the ...

Illustration shows how a smartphone magnetometer can measure a host of biomedical properties in liquid samples using a magnetized hydrogel. Nearly every modern cellphone has a built-in compass, or ...
