"However, the materials and technology required to create traditional copper-based wire superconductors ... with larger iron-based crystals within the magnet structure. The structure of the ...

A permanent magnet is always magnetic. It has an invisible magnetic field. Only certain materials, such as iron, feel a magnetic force. Permanent magnets can come in lots of different shapes and ...

The solder will bubble away the enamel and tin the copper underneath in the ... melting a small amount of solder on the iron, then push the tip of the magnet wire a small distance into the molten ...

Magnetic devices such as motors, which convert electricity into power, and transformers, which convert voltages, lose electrical energy due to the use of iron and copper as materials for their ...

On doping, the ordered magnetic state is destroyed and superconductivity sets in. Unlike in the copper oxide materials, it is possible in the same iron arsenide compound to dope either electrons ...
