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. Every day over two months, the ...

It is a common grade school experiment to wind some wire around ... The coil is fed with AC. The magnetic field from the coil induces an opposite field in the copper ring that is out of phase ...

Iron filings are ferromagnetic materials that can be temporarily magnetized by a nearby magnetic field. The slime's viscosity allows it to move slowly at first, but the magnetic force becomes stronger ...
