Explain the following terms with suitable example of each : (i) Ferromagnetism (ii) Antiferromagnetism. |
|
Answer» Solution :(i) Ferromagnetism : MATERIALS which are strongly attracted by magnetic fields are called FERROMAGNETIC materials and the property thus exhibited is called ferromagnetism. Only three ELEMENTS Fe, Co and Ni show this property at room temperature. (ii) Antiferromagnetism : SUBSTANCES which have domain structure similar to ferromagnetic substances but they are oppositely ORIENTED and cancel out each other.s magnetic moment. An example of this type of materials is MnO. |
