$$ \text { Match the following. } $$
The correct answer is

(a) Ferromagnetic materials exhibit parrallel alignment of moments resulting in large net magnetisation even in the absence of magnetic field.
(b) Moments are exactly equal but opposite, the net moment is zero. This type of magnetic ordering is called anti-ferromagnetism.
(c) In ferrimagnets, the magnetic moment are not equal and results in a net magnetic moment.
