A property of materials which are not magnetized in the absence of an external magnetic field, but in which the magnetic moments of their constituents align with and enhance an applied magnetic field; the induced magnetic field of the substance is in direct proportion to the strength of the applied magnetic field; -- opposed to diamagnetic and contrasted with ferromagnetic.
paramagnetic. Compare with diamagnetism and ferromagnetism. Paramagnetic materials are attracted to a magnetic field due to the presence of least one unpaired spin in their atoms or molecules.
Paramagnetism is a type of magnetism characterized by a positive magnetic susceptibility, so that the material becomes weakly magnetized in the direction of an external field. The magnetization disappears when the field in removed.
