Which of the following statements are correct?
(i) Ferrimagnetic substances lose ferrimagnetism on heating and become paramagnetic.
(ii) Ferrimagnetic substances do not lose ferrimagnetism on heating and remain ferrimagnetic.
(iii) Antiferromagnetic substances have domain structures similar to ferromagnetic substances and their magnetic moments are not cancelled by each other.
(iv) In ferromagnetic substances, all the domains get oriented in the direction of the magnetic field and remain as such even after removing magnetic field.
Answers (1)
The answer is the option (i, iv) There is a loss of ferrimagnetism of Ferrimagnetic substances on heating changing them into paramagnetic.
All the domains get oriented in the direction of magnetic field in ferromagnetic substances and remain as such even on removal of the magnetic field.
