paramagnetism

The phenomena exhibited by paramagnetic substances. See diamagnetism.

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.

the tendency of magnetic dipoles to align with an external magnetic field; materials that exhibit this tendency become temporary magnets

materials like aluminum or platinum become magnetized in a magnetic field but it disappears when the field is removed
