NCERT solutions for class 12 Physics chapter 5 Magnetism and Matter

 

NCERT solutions for class 12 Physics chapter 5 Magnetism and Matter: You have studied in the first chapter that isolated charge can be obtained. Can you obtain magnetic monopole? If we cut a magnet into several parts each part will act as a magnet with south and north pole or magnetic dipole. This shows that magnetic monopole cannot exist. And you will study such properties of the magnet in NCERT solutions for class 12 Physics chapter 5 Magnetism and Matter. While studying this chapter you can compare it with electrostatics. The comparison of electric dipole in chapter 1 and magnetic dipole in NCERT solutions for class 12 Physics chapter 5 Magnetism and Matter is given below.
