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.

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

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 ...

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 ...

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 ...

This project combines some of the most exciting aspects of DIY experiments. Lego, high voltage, and a powerful magnetic field. The idea is simple yet intriguing, using a copper coil, capacitors, and a ...
