Question
Explain the following with suitable examples:
Paramagnetism.
✓

Answer

Paramagnetism:Few substances like $O_2, Cu^{2+}, Fe^{3+}, Cr^{3+}$ are weekly attracted by a magnetic field.
These substabces are magnetised in a magnetic field in the same direction. When we remove magnetic field ,they lose their magnetism. paramagnetism is takes place due to presence of one or more unpaired electrons. These unpaired electron are attracted by the magnetic field.
