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.

Using battery holders and bulb holders can make it easier to experiment with circuits ... by concentrating the magnetic field. In this activity campers coil wire around an iron nail and run ...

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 ...

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 ...

In this facility a conductive sample is placed in a coil and processed containerless ... scientists to process the sample without contact to a crucible and with low magnetic field strengths compared ...
