Observation
This  is another favorites question among candidates. Most of the candidates got  their bearings right to score full marks. Some lost marks by using the word  “magnet” instead of magnetic; “diamagnet” instead of “diamagnetic”.
 
The  expected answer is: 
Magnetic  materials (Classes)                                                           
            -    Diamagnetic
              -   Paramagnetic
              -   Ferro-magnetic
