Paramagnetic materials are characterized by atoms or molecules that possess permanent magnetic dipole moments. In the presence of an external magnetic field, these dipoles tend to align with the field, resulting in a positive magnetic susceptibility.123
When placed in a nonuniform magnetic field, a paramagnetic material experiences a net force that draws it toward the region of higher magnetic field strength. This occurs because the material's induced magnetization—which is aligned with the external field—is attracted to the stronger part of the field. Consequently, paramagnetic substances are described as being weakly attracted by a strong magnet.423
