Define : (1) ferromagnetic (2) paramagnetic (3) diamagnetic substances

Three identical bars A, B and C are made of different magnetic materials. When kept in a uniform magnetic field, the field lines around them look as follows: Make the correspondence of these bars with their material being diamagnetic (D), ferromagnetic (F) and paramagnetic (P):

A: Above curie-point a ferromagnetic substance behaves as a paramagnetic substance. R: Magnetic susceptibility of a diamagnetic substance increases with rise in temperature.
