NOAA scientists have spent decades tracking how magnetic north wanders, but recent modeling shows a pole moving in ways ...
The magnetic compass that birds use for orientation is affected by polarized light. That is the finding of researchers in Sweden, who studied zebra finches navigating a simple maze and found that the ...
Earth's magnetic field is generated by the churn of its liquid nickel-iron outer core, but it is not a constant feature. Every so often, the magnetic north and south poles swap places in what are ...
Migratory birds make epic journeys of thousands of kilometers each year, navigating with the help of Earth’s magnetic field. Yet the mechanism behind the biological compass that enables them to ...
The Earth's magnetic field is changing at an increasing rate, throwing off airports and altering the aurora borealis -- and its effect on ordinary compasses could mean the difference between homeward ...
