Hint:Basic properties of paramagnetic substance ferromagnetic and diamagnetic, like in presence of magnetic field, susceptibility and others.
Complete step by step answer:
The distinction between Ferro, para and diamagnetism is as given below
Note:Remember that diamagnetism arises in a paired electron system which thus results in net zero magnetic moment. While paramagnetism is generally due to unpaired electrons and their domains try to align them in the direction of field applied.
Complete step by step answer:
The distinction between Ferro, para and diamagnetism is as given below
Property | Diamagnetism | Paramagnetism | Ferromagnetism |
Effect of magnets | They are weakly repelled by magnets | They are weakly attracted by magnets | They are strongly attracted by magnets |
Susceptibility | Small and negative i.e. $ - 1 \leqslant {X_m} < 0$ | Small and positive i.e. $0 < {x_m} < E$where E is a small number | Very large and positive ${X_m} > 1000$ |
Hysteresis effect | Magnetic vectors show no hysteresis. | Magnetic vector shows no hysteresis | Magnetic vector shows hysteresis |
In external magnetic field | It acquires weak magnetisation in the opposite direction to the magnetising field. | It acquires weak magnetisation in the direction of the magnetising field. | It acquires strong magnetisation in the direction of the magnetising field. |
In non-uniform magnetic field | It tends to move slowly from the stronger to the weaker parts of the field. | It tends to move slowly from weak to the stronger parts of the field. | It tends to move quickly from weaker to stronger pails of the field. |
Effect of temperature | Susceptibility is independent of temperature | Susceptibility varies inversely astemperature ${x_m}\alpha \dfrac{1}{T}$ | Susceptibility decreases with temperature in a complex manner${x_x}\alpha \dfrac{1}{T}\left( {T > {T_c}} \right)$ |
Removal of magnetising field | Magnetisation lasts as long as the magnetic field is applied | As soon as the field is room, its magnetisation is lost | In it, magnetisation is retained even after the removal of the magnetising field |
Note:Remember that diamagnetism arises in a paired electron system which thus results in net zero magnetic moment. While paramagnetism is generally due to unpaired electrons and their domains try to align them in the direction of field applied.
