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.

This coil, when activated, generates a precise magnetic field that stimulates specific brain regions. “The magnetic field generated by the coil is approximately 500 milliTesla (mT), about 10 ...

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 ...

Dancing turtles have proved for the first time that some animals use Earth's magnetic field to create a personal map of their ...

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 ...

It uses a number of coils to produce a magnetic field to levitate the 3D printed ... Power is transmitted with a further larger coil, much as in a wireless phone charger. This is picked up by ...

Previous turtle experiments have used magnetic intensities with at least a 2,000-nanotesla field difference ... the Atlantic Ocean and developed a coil system to produce fields between 2,000 ...

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 magnetic field of the Atlantic Ocean. - 'Turtle dance' - Every day over ...
