A rubbermagnet is a metalloid magnet which is made from an organic polymer,take polyaniline for example ,which is a combination of emeraldine based on polyailine.
   PANi is a conductive polymer which is stable in air, when combined with free radical, they will form TCNQ, it can mimic the mechanism of metallic magnet. The magnetic nature caused by the pi-conjugated nitrogen which contains backbone that combined with molecular charges transfer side groups. These natures cause the molecule to own a high density of localized spins that can give rise to coupling of the magnetic field. 
   Plastic magnet could be used in computer hardware, for example as disc driver and medical devices,such as cochlear implants and pacemakers. recently, fridge magnets are very popular. they can be used as gifts, souvenirs, advertisement ect.
