Answers (1)

(ii) Paramagnetism : 

The substances that are weakly attracted by a magnetic field are called paramagnetic substances. They are magnetised in a magnetic field in the same direction. They lose their magnetism in the absence of a magnetic field. Paramagnetism is due to the presence of one or more unpaired electrons which are attracted by the magnetic field. Example:O_2,Cu_2^+ , Fe_3^+ , Cr_3^+.
