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

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 ...

Although the Earth’s magnetic field is reliable enough for navigation and is also essential for blocking harmful solar emissions and for improving radio communications, it’s not a uniform strength ...

A team of physicists and engineers at the CU Boulder has discovered a new way to measure the orientation of magnetic fields using what may be the tiniest compasses around—atoms. The group’s findings ...

Atomic physicists “are jacks of all trades,” according to Alex Sushkov. “You have to have the idea, design the experiment, build the experiment, run the experiment, fix everything, take data, analyze ...

Researchers at Paul Scherrer Institute PSI have demonstrated an innovative method to control magnetism in materials using an energy-efficient electric field. The discovery focuses on materials known ...
