A coil of wire, or solenoid, consists of a wire coiled up into a spiral shape. When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet.

For the experiment, the scientists put young loggerhead turtles in a tank surrounded by a magnetic coil that replicated the ...

Sea turtles are capable of creating GPS-like magnetic maps to guide them back to foraging grounds, and they do a little dance when they recognize those spots ...

As you may recall from Physics 101, a changing magnetic field (like when you slide a bar magnet through a copper coil) induces an electric current. At planetary scale, Earth’s magnetic field induces ...

For the experiment, the scientists put young loggerhead turtles in a tank surrounded by a magnetic coil that replicated the magnetic field of the Atlantic Ocean. - 'Turtle dance' - Every day over ...

The magnetic field generated by the coil is approximately 500 milliTesla (mT), about 10 times stronger than the Earth's magnetic field, which is approximately 50 microTesla (µT). For reference ...
