We’ve seen this sort of device before, and the basic construction is extremely similar – a laser shines on a mirror attached to magnets. When a change occurs in the local magnetic field ...

the magnetic north pole’s position is determined by Earth’s magnetic field, which is in constant motion. Over the past few decades, magnetic north’s movement has been unprecedented — it ...

“The current behaviour of magnetic north is something that we have never observed before,” William Brown, a global geomagnetic field modeler at the British Geological Survey, said in a statemen ...

The hypothesis, however, that the interplay between electric and magnetic fields could explain the preference for one or the other mirror-image form of a molecule—so-called enantiomers—emerged ...
