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 ...

Earth is surrounded by a magnetic field generated by electric currents from within the planet. Compasses take advantage of this field to identify north and serve as a navigational aid. But one social ...

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 ...

Loggerhead sea turtles (Caretta caretta) can learn to associate food with the geomagnetic signatures of various oceanic regions, suggesting that they are able to find known foraging areas using an ...

Earth's magnetic field is weakening and its north pole is shifting faster than previously observed, raising concerns about a potential geomagnetic reversal. Geomagnetic reversals, where the magnetic ...
