The needle will turn and then come to a complete stop. It will be facing magnetic north. You can check this by placing the compass next to the bowl. The needle is being affected by the Earth’s ...

Physicists and engineers have developed a groundbreaking method to measure magnetic field orientation using atoms as tiny ...

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 ...

If all the compasses in the world started pointing south rather than north, many people might think something very strange, very unusual, and possibly very dangerous was going on. Doomsayers would ...
