# 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 given in the figure . Make the correspondence of these bars with their material being diamagnetic (D), ferromagnetic (F) and paramagnetic (P) .A↔F,B↔D,C↔PA↔D,B↔P,C↔FA↔F,B↔P,C↔DA↔P,B↔F,C↔D
