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.
materials like aluminum or platinum become magnetized in a magnetic field but it disappears when the field is removed
_The atoms or molecules of a substancethat have a net orbital or spin magnetic moment end are capable of being aligned in the direction of the applied field. (seetext).
a relatively weak form of magnetism that results from the independent alignment of atomic dipoles (magnetic) with an applied magnetic field.
Attraction toward a magnetic field, stronger than diamagnetism, but still weak compared to ferromagnetism.
Paramagnetism is a form of magnetism which occurs only in the presence of an externally applied magnetic field. Paramagnetic materials are attracted to magnetic fields, hence have a relative magnetic permeability greater than one (or, equivalently, a positive magnetic susceptibility). However, unlike ferromagnets which are also attracted to magnetic fields, paramagnets do not retain any magnetisation in the absence of an externally applied magnetic field.
