Introduction of NCERT Solutions for class 12 Physics Chapter 5 Magnetism and Matter

how the Biot-Savart law determines the magnetic field produced by a steady current, but we assumed that any matter that might affect the field was far away and negligible. In other words, we only described a magnetic field in a vacuum. But the presence of matter solids, liquids, or gases changes the magnetic field from what it would be in a vacuum. In this sense, all materials are magnetic materials. They change the field because they contain microscopic, atomic-scale currents and magnets which are themselves sources of B. In this chapter, we study why the field changes and how to calculate the new field. We shall acquire a qualitative and semiquantitative understanding of magnetic interactions in the matter, learn how and why magnetic properties vary among materials and look at some applications. Most magnetic materials-diamagnetic or paramagnetic materials-interact with externally applied fields in the manner just described.
