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”.

            -   Diamagnetic
             -   Paramagnetic
             -   Ferro-magnetic
