allerySubstances that get weakly magnetised in an external field are called:
AParasitical
BParabolical
CParamagnetic
DParadoxical
Answer & Solution
Correct answer: C. Paramagnetic
1. Materials are classed by how strongly they respond to a field.
2. One class responds only faintly and in the same direction.
3. Paramagnetic substances are those which get weakly magnetised when placed in an external magnetic field.
4. So the answer is paramagnetic.
