A separate experiment testing the turtles' inner compasses was more successful. In a tank replicating the magnetic conditions of the West African archipelago Cape Verde, the radiofrequency emissions ...

If all the compasses in the world started pointing ... Such reversals in the Earth's magnetic field, they'd tell you, are, roughly speaking, as common as ice ages. That is, they're terrifically ...

Magnetotactic bacteria synthesize magnetic iron nanominerals, which function as tiny compasses that allow the microbes to navigate using Earth's geomagnetic field. Earth's iron cycle is a very ...

When I learned recently that our planet's magnetic shield is rapidly weakening and may be ready to reverse its polarity, causing compasses to point south, I immediately wondered what that would ...

A permanent magnet is always magnetic. It has an invisible magnetic field. Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and ...

Magnetic world The research emerges, in part, from Knappe's long-running goal to explore the magnetic environment surrounding us. "What magnetic imaging allows us to do is measure sources that are ...

The planet's magnetic North Pole, where compasses point, has been unexpectedly moving toward Russia. While shifting is not a rare occurrence, the pole is moving both faster and differently than it ...
