Paramagnetic materials are those diamagnetic materials in which each individual atom or molecule or ion has a net non-zero magnetic moment of its own.
When a paramagnetic material is placed in an external magnetic field of induction (B), it tries to align the individual dipole moments in the direction of the field. For strong value of B, there is a net average magnetic dipole moment density in the direction of B.
Therefore, in other words, paramagnetic materials are those magnetic materials which when placed in a magnetic field, become weakly magnetized, in the direction of the applied external field.
Examples: aluminium, platinum, chromium, manganese etc.
