A diamagnetic material is one in which the electrons begin moving when it's place in a magnetic field. These moving electric charges create a second magnetic field that partially cancels the original field. A diamagnetic magnetic field partially shields itself from magnetism when it's exposed to a magnetic field.
A paramagnetic material is one in which individual magnetic electrons respond magnetically to any external magnetic field. It becomes weakly magnetic when it's exposed to a magnetic field. Unlike a ferromagnetic material, a paramagnetic material has no intrinsic magnetic order before it's exposed to an external field.
