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 ...

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 ...

Using a magnetic compass to calculate the current in a wire. Learn how magnetic fields, compass deflection, and basic electromagnetism principles connect in a practical physics experiment.

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 ...

Nocturnal insects may use both Earth's magnetic field and visual cues to guide their migratory flight behaviors, according to recent findings. The research, published in eLife, presents compelling ...

Many migratory birds use Earth’s magnetic field as a compass, but some can also use information from that field to determine more or less where they are on a mental map. Eurasian reed warblers ...

The magnetic compass is the last unknown sense in migrating animals. For some scientists, the monarch butterfly is leading the way. The magnetic compass is the last unknown sense in migrating animals.

Migratory bats use a magnetic sense to navigate long distances, calibrating their internal compass based on the position of the setting sun each evening. Many animals may use Earth’s magnetic field ...

For desert ants, Earth’s magnetic field isn’t just a compass: It may also sculpt their brains. Stepping outside their nest for the first time, young ants need to learn how to forage. The ants train ...
