Question

Statement-I : The ferromagnetic property depends on temperature. At high temperature, ferromagnet becomes paramagnet.\ Statement-II : At high temperature, the domain wall area of a ferromagnetic substance increases.\

Professor PC Thomas Classes · Answer

(c) : In ferromagnetic material, all the molecular magnetic dipoles are pointed in the same direction. When the ferromagnetic material heated, all magnetic dipoles are distributed and get disoriented. Due to which the net magnetic dipole moment becomes very less, so that they behave as paramagnetic material. So, statement I is true.\
