write about the Paramagnetic solids :
Answers
Answer:
The substances with unpaired electrons are weakly attracted by magnetic field. These substances are called paramagnetic substances.
The spinning of unpaired electron gives rise to a magnetic moment. The substance is attracted by magnetic field because of magnetic moment. It is important to understand that these substances exhibit magnetism in presence of external magnetic field only. They lose magnetism when the external magnetic field is removed.
Answer:
Explanation:
Paramagnetic
These substances are weakly magnetized in an external magnetic field. The direction is the same direction of the magnetic field. So they gain a net magnetization When we remove the paramagnetic substance from the field, the alignment of electrons is interrupted and the substance will lose its magnetic property. Thus paramagnetic substances are not permanent magnets.
Paramagnetism is due to at least one pair of unpaired electrons in its orbit shell which get magnetized in the magnetic field. Some common examples are O2, Cu2 etc. These paramagnetic substances find a variety of applications in electronics.
