Websusceptibility is however is also very small: 10-4 to 10-5. The best-known examples of paramagnetic materials are the ions of transition and rare-earth ions. The fact that these ions have incomplete atomic shells is what is responsible for their paramagnetic behavior. In all other materials equation (4) breaks down as temperature decreases. WebParamagnetic material: Magnetic materials which align with the magnetic field are known as paramagnetic materials. Magnetic susceptibility is χ>0 which means it is always a small positive value for paramagnetic materials. These materials are temperature dependent and are weekly attracted by magnets with relative permeability 1.00001 to 1.003.
