British researchers from the University of Durham (University of Durham) have created the world's first plastic magnet that "works" at room temperature.

To date the establishment of said plastic magnet at least ten groups of scientists, however, they have received or materials needed low temperatures, or they were too weak magnetism.

So scientists from Durham can safely say that made the first plastic magnet that can be used in everyday life.

For example, this polymer can cover computer hard drives, thereby increasing their performance.

Zaid Naveed (Naveed Zaidi) and his colleagues created a new polymer of the two formulations: this metal electrical conductor PANi (emeraldine base polyaniline) and forming charged particles TCNQ (tetracyanoquinodimethane).

In conventional magnet field is the same orientation of the magnetic moments of the individual atoms or molecules, and British scientists in a polymer decided to achieve the same effect for free radicals.

At first, the new material was too little evidence of magnetism, and after three months, the researchers were ready to stop the experiments. But then just decided to take a break.

To their joy for a few months in the polymer developed magnetic properties.

Although the weak magnetism of the material compared to conventional metal magnets, the researchers are confident that they can improve the performance of polymer. However, it may take years.
