Which of the following substances does not posses a net magnetic dipole moment in magnetic field?
Which of the following substances does not posses a net magnetic dipole moment in magnetic field?
The correct option is D Antiferromagnetic
Paramagnetic substances are magnetised in the same direction as the magnetic filed. Thus, they have a net magnetic moment.
In ferromagnetic substance, in presence of an applied field, domains get aligned with the applied magnetic field. The combined effect of the atomic magnetic moments results in a relatively large magnetization.
In ferrimagenetic substance, due to the unequal magnetic moments in opposite direction, resulting in a net magnetic moment in one direction. Magnetic moments of the domains are aligned in parallel and anti-parallel directions in unequal numbers.
Antiferromagnetic substances possess unpaired electrons but they do not possess net magnetic moment due to presence of equal and opposite magnetic moments.
Some metals, alloys and salts of transition elements such as MnO, MnSe, etc. are examples of antiferromagnetic substances.
Thus, option (d) is correct.
