Question

The relative magnetic permeability of a magnetic material is 800.

Answer 1

magnetic material having relative permeability of 800 would be classified as a ferromagnet. A few examples of such material's include iron and nickel. Its two properties are: (1) All ferromagnetic material's become paramagnetic when heated to a temperature above the Curie temperature (Tc).

Answer 2

Relative permeability of a paramagnetic material is> 1    where as Relative permeability of a ferromagnetic material is >1000 so here the magnetic nature is Paramagnetic     Now two properties are  (1) They have tendency to move from a weak magnetic field region to a strong magnetic field region                 (2)  when a paramagnetic substance is placed in an external field the field lines get concentrated inside the material , and the field inside the material is enhanced  ........  HOPE THIS HELPS ....
